rremiker,
The only thing I can think of is that your Forerunner may have some bad data and is choking the Garmin Communicator plugin. You can try doing a hard reset (hold down the Mode and Reset buttons for several seconds) and see if that makes a difference. If that doesn't work, you may want to delete all the workouts from the watch and see if that helps.
