This is pathetic. I have yet to upload data for over a month now, on my watch and my fiance's watch as well. The ANT+ was working fine, then we swapped to Garmin Express and removed everything. It glitchy the first few times we transferred data a few months ago. It came to the point that I had to remove the device and resync each time to upload information. Now, a month later. I cannot transfer my data. My express service seems to be in an eternal transferring data state, on the first activity to load. I tried deleting that activity, thinking it might have corrupted, but still nothing. I have uninstalled everything garmin on my computer and reinstalled express. To no success, it is still hung up on transferring an activity I DELETED.
I am out of ideas, other than finding another company that doesn't have such pitiful software.
