Hi,
I had a couple of activities on my 910XT however I had to reinstall my PC and Garmin Connect.
After pairing my Forerunner with the PC it would only synch activities that took I recorded after pairing.
I can't get activities recorded last week to be uploaded/synced to my garmin connect profile. Please fix ASAP because it sucks and I am terribly annoyed because the previous version of Garmin Express did not have this problem and why you need to change something that worked well. Cheers.
