Could some one help me sort out a problem uploading to gp3s.com please? I useless at these things.

Basically, after downloading from my SD card to gpsactionreply and clicking send to gp3s.com server, I get this message:







This only started happening yesterday. I took the gps out again to make a mock session and tried to upload it, same problem.

Strange thing is, I can still upload previous session without any problem??

Does this sound like my GT31 has died and is not recording to the SD card properly (hence why I can upload old session)?

Many thanks:)
