CMS-50F not working?

I haven't been tracking my data for about a year now. I had become completely OCD about my data so I decided to go cold turkey

Stopped by the other day and got motivated and got my CMS 50F oximeter out and downloaded the Sleepyhead software ( fantastic much better than Rescan ).

I searched and downloaded the latest software for the CMS 50F but I can't seem to get it to work.

Since the days of OCD about my data I have built a new computer using Windows 7 64 bit with a SSD C drive and I put most programs on D to save room on the small( ish ) C drive.
When I installed a driver it said it was using COM 5.
But I can't get the SO2 software to let me tell it which COM port to use.
When I connect the oximeter and set it to upload I just get a message from the SO2 software that no device is found.

I installed the driver in C drive but installed the software on D drive.

Does it have to be installed on C?

I tried deleting it and installing the original software that came with it but that didn't work either so I figured I might as well try to solve the problems with the newer versions so i deleted the original and installed the new sotware again.

Sleepyhead works fine but can't get the oximeter to work.

Any suggestions?

Look for tutorial on the pulse ox store web site. I had the same problem and was starting the wrong program to extract the data.

Thanks for the reply.

Got it working now.

When I went to install the latest software again this morning it popped up a message that a newer driver was installed and that I should remove the driver 6.4.

So I did and bingo it took off working!!

Bad news is that when imported into Sleepyhead it tells me I was desaturated 34.8% of the time and on the graph it shows I was clear down in the 80% range quite a bit.
I suspect that is why even though I use the S9 Autoset religiously and never take the mask off, I have a lot of daytime sleepyness.. some days are better than others.

I'm going to see about emailing screenshots to my sleepdoc.

I got a feeling I need to be on O2.
