I have a Cambridge GPS-NAV. I am trying to download a flight log. It looks like the Aero Explorer software is reading it from the GPS-NAV ok, but then a dialog box pops up with an error msg "Error writing flight log to disk."

I was able to download logs earlier this year, but was running on a different PC with Windows 7 (I think). I now am using a machine with Windows 8.1. I did try turning off the Avast antivirus software with no luck.

I was able to download the log via SeeYou but I wanted to download it via the Cambridge software for use as an official flight for badge purposes.

Any ideas on what to try other than finding a PC with an older version of Windows? (Or upgrading my logger?)
