Based on the error log, it seems like some kind of internal problem in the Garmin plugin. It is hard to say exactly what is causing this.
Some things to try:
- upgrade your plugin from 4.0.3 to 4.0.4.
- if your 910 isn't new, you should try clearing out the older sessions.
- sometimes there are problems with particular sessions. try recording a very short test session, and see if you can transfer only that one.
- if you have a tcx file, try importing that directly. you can export tcx from Garmin Connect, or find them in your ant agent folder, something like c:\users\[username]\AppData\Roaming\GARMIN\Devices\[number]\History\
- if you have a tcx file, but it won't upload directly, email me a copy and I will take a look.
- if you have a ton of files in your ant agent history folder, you can archive most of them to some other place.
