Are you on dial-up?
It happens to me too.
Always on upload I start it and IMMEDIATELY check the error log.
If I see the 910 error I drop the dial-up connection straight away.
I have sometimes managed to use
.\foldtrajlite - purgeuploadlist xxxx
Look into the error log to see when the first 910 popped up.
Replace the xxxx with as low a number as the error log suggests you can get away with.
PM me your handle and I'll bung it on a couple of boxen to make up for your loss.
