Gary,
I think you mean you were uploading the file from your cambridge logger
not from WinPilot's built-in logger.

To answer Paul's question though, WinPilot is still on the OLC Approved
Software list (http://www.onlinecontest.org/validate.php) though many
others are. I believe the only reason for this is because Jerry hasn't
added a security signature ("G" Records) to his IGC files and then
produced a corresponding "VALI" program to validate the IGC files. If
he did this and sent it to the OLC, they would then be able to validate
WinPilot log files. They would then get the blue "V" for validation
which is just fine. This is what I did with SoarPilot a couple of
years ago and it SP's log files validate just fine.

Later!
