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.

If SeeYou works, just use it.Â* No requirement to use Cambridge software.
Â*Check the dates, many old recorders will show a date 18 years in the
past, invalidating the log.Â* Submit to OLC as an easy check for IGC
security being valid.

Get rid of Windows 8.1, it was a disaster.Â* M$ tried to upgrade everyone
to 10.Â* But using obsolete software and hardware with modern OS's leads
to lots of problems.Â* Update to something like an LXNAV Nano, which acts
like a USB memory device and lets you just copy the file out easily.
Trying to use RS-232 devices in this day and age is a waste of time.

If you happen to have PowerFlarm, then enabling the igc logging is
another good alternative. This saved me when the RS-232 link from my
CAI 302 into my Tophat computer stopped working at a camp this year.

The GPS-NAV puts out a binary .cai file, which is secure but
proprietary. Has to be converted to .igc with an external program.
Definitely time to move on.

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