I'm having the same problem uploading a pair of log files from a
friend's old Model 20. I've tried uploading "by hand" via the OLC
flight claim page, and massaging all of the data fields by hand. I've
tried uploading with SeeYou 3.1, but when the OLC flight claim page
comes up, it has different coordinates for the turnpoints than SeeYou
selected. When I change those coordinates to match what SeeYou came up
with, it comes back with a message saying "No valid fixes after end of
flight" or something similar. I am a computer programmer by trade, and
I manage a couple of web sites, so I like to think there isn't operator
error involved here.

The only thing I can find that might be causing the trouble is that in
each log file, there are about a half dozen "B" records with east
longitudes instead of west. I think that might be confusing the server
software. But when I edit the file and remove or modify those records,
OLC complains about something else ...
