"No therapy data is available" Encore Viewer

[Captain_Midnight]

I now have an odd Encore Viewer issue. My previous nights data do show up in my EV download, (but tomorrow it will, and tonight's data won't). The software somehow chooses to display info a day late, leaving me only with b the ungrammatical message "No therapy data is available" for the .

I can live with this, but I'd love to fix it, or at least to make sense of it.

For a bit of background, I switched data cards a few nights back. And that just seemed to put the machine in a reluctant-to-tell-me-until-tomorrow mode. Switching back to the old card does not change the data reporting tardiness.

Has anyone else experienced this? Any thoughts on how to catch my little PR-one up to the present?

Thanks in advance --

I had a similar problem when I had to get a new machine with it's new data card. I got it to work be adding a new user on Encore Viewer and using the new card with that user name. Hope this helps Kathy

Ok, this may or may not be relevant for fixing either Captain_Midnight or mayondair's problems with "No therapy data is available" messages, but I recently fixed a similar sounding problem of my own in Encore.

I recently had my PR S1 BiPAP switched out due to a warranty issue. The tech set the new machine up a few days before I had a chance to pick up the machine and I continued to use the old one (and the old one's SD card) in the meantime.

Soon as I uploaded the data from the new machine, there was that "No therapy data is available" on a handful of dates. When I looked at the files ON the SD card, the problem became crystal clear:

The tech set the machine up on April 22 and the first set of files in the directory where the data is written were dated 04/22/2011. The next set of files---generated the first night I used the machine were dated 04/28/2011 and corresponded to data generated for the night of April 27--28 (I go to bed after midnight). And the missing data was for April 22, 23, 24, 25, and 26.

So this is what I did:

• First I deleted the three (tiny) files on the new card dated 04/22/2011 using my computer. And then unmounted the (new) SD card from the computer.
  
  Next I inserted the old SD card and downloaded its data back into Encore Viewer. At this point, I now had Therapy data for the missing dates. And I unmounted that SD card.
  
  Finally I re-inserted the new SD card and downloaded its data into Encore Viewer. This time, Encore treated the new data period correctly as 04/27/2011 to 05/01/2011 instead of incorrectly as 04/22/2011 to 05/01/2011. And I can now see ALL the data in Encore Viewer by selecting the appropriate data ranges.

So check the new card and see if there's a big gap between the date of the first set of three files on the card and the ones where the data starts. Chances are if there is such a gap, this fix might address your problem.

Thanks for the responses, I have success to report.

Simply by creating a new user in EV, the issue was settled with no data lost.

As an aside, I re-read my initial post, and I'm impressed that you both understood what I (rather hastily) wrote. When in a hurry, I follow a simple format: 1. Write the post, 2. Submit, 3. sometime later, carefully proof read.

When I ran into a 'no data' problem on the report, I just did a second download. That worked. I'm sure Captain_Midnight tried that right off the bat, though. Just thought I'd mention a simple action that might help some folks.

This problem first happened after I added a new user. I added my mother and downloaded her data for her. Next time I checked my card (after selecting my own user id), I saw mostly 'no data' entries in the report. I closed the report and clicked the download icon again. Then the data came in. (Background: I'm running Encore Viewer on a Windows 7 64-bit machine. I initially installed software on a 32-bit XP machine and then copied the Program Files folder for Encore Viewer to my new machine with no problems other than the one in this post.)

The above solutions are tantalizingly close to what I need to solve a similar problem, except they do not work for me. My data is faithfully displayed from April 2010 through May 2, 2011. After that, every single date is marked "No therapy data is available" in the Encore Viewer.

Looking at the raw SD card files from Windows XP Explorer shows that all the dates are present in the p1 directory with none missing. However, there is a discrepancy as shown below:

05/02/2011 08:07 AM......................0 0000000763.005
05/04/2011 04:39 AM...................385 0000000763.001
05/04/2011 04:39 AM.................4,977 0000000763.002

05/04/2011 01:50 PM..............106,440 0000000768.005
05/04/2011 01:50 PM.....................77 0000000768.001
05/04/2011 01:50 PM.................2,383 0000000768.002

Note that the 05/02/2011 .005 file is empty (0 byte) and files .001 and .002 are dated 05/04/2011 instead. That seems to be where the problem lies. Not knowing the internal layout of any of those 3 files, I am not sure how to correct the problem.

Follow up to my previous post.

I decided to "take the bull by the horns" and deleted the 000000763.001/002/005 files from my SD card. Had this worked, I would have missed a maximum of 2 days worth of data, which is not the end of the world. However, now Encore Viewer refuses to recognize any data past May 2, 2011.

As I looked at the Properties.txt control file, I noticed several date fields, one of which says: "LastDate=1305504000". That should translate pretty close to May 2, 2011. In order to verify my hypothesis, I ran the number into Microsoft Excel 2003 and entered 1305504000 in one of the cells and identified it as a number format with no decimals. Then, using the Format menu, I applied a Date format in order to force translation from 130550400 to an "mm/dd/yyyy" representation. That yelded an infinite number. I then tried various subsets of 1305504000 and obtained the results shown below, none of which gives me close to a valid answer.

4000........12/13/1910 (too far back)
13055.......09/28/1935 (in the right direction, but still too far back)
130550......06/06/2257 (too far into the future)

The one number that would yeld 05/02/2011 is 40665. Unfortunately, this is not what Encore Viewer uses in my file.

What I need is the algorithm to translate 1305504000 into a valid date. If indeed the result is close to May 02, 2011, then resetting the entry to the actual date of my last session (May 15, 2011) might correct the problem of Encore Viewer not displaying my data past May 02.

Has anyone cracked that code?

Additional follow up to my previous posts.

I called the Respironics support line Tuesday morning. Their recording indicated they would call me back within 2 business days. They called back the next day at which time I spoke with a technician who was very polite and listened carefully to my problem - but didn't have any suggestion on how to resolve the issue at hand.

Repeated searches on this website as well as on Google have not yelded any results either. I am at my wits ends at this point.

Problem fixed!

All along I thought the Encore Viewer software was processing data directly from the SD card. In reality, it stores its successive downloads to (in my case, using XP) the following directory:

C:\Documents and Settings\"my User name here"\Local Settings\Application Data\Respironics\EncoreViewer\Data

The above location had accumulated a number of downloads. Data corruption resided there, not on the SD card as I had thought all along.
To resolve the issue, I temporarily renamed the "\Data" directory to "\xData" and created a new empty "\Data" directory. At this point I downloaded the data from my SD card, then generated a full report going back to April 2010 (when I started therapy).

It worked! All my data is there. No more corrupted data. At this point the "xData" directory is no longer needed and can safely be deleted.
