JediMark's info on F&P gives it a grade of D.
With the following remarks:
Manufacturer failed to openly document this format.
Fails to keep flow data, even with a potentially huge datastick.
Very low resolution (2 minutes) event data, can't overlay over flow waveform.
Hideously stupid timestamp format.
With emphasis on flow waveform data structure:
Perhaps F&P has some sort of Y2K15 bug?

Okay, can we find out what program or tool to use, in order to read the 3800KB FLW000x.FPH flow files?
Per below, there ought to be some way to look at the the FLW000x.FPH files, and to compare the 32bit timestamp words written now to the 32bit timestamp words written prior to Dec 30.
I happen to have complete data stick archives from November and December. If the FLW000x.FPH files on the stick today do not possess 2015 timestamps, then the machine is no longer writing the files. If they do possess current timestamps, then we know the machine is still writing flow rate data, but that Sleepyhead can no longer import them.
"This FLW000?.FPH files are constant 3.7Mb in size, and will start a new one when it's full, cycling between 7 files.
Begins with normal 0x200 byte header Followed by a 32bit timestamp, and multiple chunks of sample data for a single session.
Each chunk consists of a repeating pattern of
50 16bit samples,
followed by the 16bit pressure value,
8 bit leak/adjustment value
and a 16bit (0xffff) end-of-record marker
Each chunk ends after the last 0xffff marker with the 16bit end-of-chunk code 0xff7f, and zero padding to the end of a 512byte page, followed by the next block if any (or zeroes till the end of file)
Unsure of any timing issues in between chunks.. (possibly chunks restart aligned to a 2 or 6 minute boundary)"
I suspect that SH simply doesn't understand the data in 2015 due to the undocumented format. You might try changing the date on the machine to 2014 and see if the flow data comes back. (Assuming you can change the date on the Icon).

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
