I copied that data (about a month's worth) to a USB flash drive and am wondering if it's possible to import data from the flash drive into SleepyHead. I tried it and the program crashed.
I have looked for existing threads/discussions about this, but only seem to see instructions to "import from the SD card" but not a specific statement that SleepyHead WON'T import data except from an SD card.
The only SD card that I have is the one in my CPAP machine, and I would have to copy the old data back onto it and then try importing. I'm hesitant to do that for fear of accidentally damaging the new data on the card. I'm not clear about whether the new data is stored in the CPAP machine as well as on the SD card.
