Reposting this because it has gotten worse - after 2 or 3 tries my computer crashes and reboots.
I put my 305 on the cradle, open Garmin Connect and click the Upload button. It goes into Search For Device, but instead of finding my 305 it finds Memory Card (G:\) If I remove it from the computer, plug it back in and click Upload again it finds my device. But when I click Upload All New Activities the Reading Activities From Chuck starts, but it gets to anywhere from 8 to 60% and the 305 beeps and says Transfer Complete even though it is frozen on Garmin Connect. Usually after about an hour of doing this it will eventually complete. When it does it pops up a screen full of error messages and sure enough the activity is not on the activity list. Eventually it completes and my activity loads, but by that time I am thoroughly frustrated. I am pretty sure I have the latest version of GC (although I can't find out for the life of me how to check the version number). I have tried it in Firefox, IE and Chrome with the same results. Any ideas!
