Hi all. I've been studying many of the threads herein, and believe I have a similar situation; however, no solution thus far. Specifically:
1. I've installed Garmin Express (rev. 3.1.4.0).
2. I've an account on the Gramin Connect Website and can login successfully.
3. My Forerunner 310XT pairs beautifully (I am able to add the device) and shares data with my MacBook Air (running OSX 10.9.2).
4. I can "apparently" login into my existing account on the Garmin Connect Website from the Garmin Express Application; however...the Garmin Express software simply hangs on the "Loading Connect data..." and spins indefinitely.
Please note that I have deleted all Garmin instances within the Keychain Access Utility - again to no avail.
Any suggestions or assistance would be most welcome.
Thank you,
David
