SleepyHead and PR System One REMstar BiPAP

I downloaded SleepyHead to try out against Encore but when I go to import the data I get "couldn't find any matching data at this location".
I am using a PR System One REMstar BiPAP Auto with Bi-Flex but I don't know if it's compatible with SleepyHead although the CPAP version seems to be.
Am I doing something wrong?

I suspect you are not pointing it to the proper location for the import of data. Common mistake.
It says "folder" and most people go to the folder and that is too far.
My SD card is in E drive....see image.
Use the SD card in whatever drive as the selected folder and then it should work. If it says P Series in the Folder line...you have gone to far into the folder.
It will work with the PR S1 BiPap for sure..because I have one and it works fine.

That's what I was doing, I was going to far.
thanks
