@PHILIPSHAMBROOK possibly the most unhelpful comment I've seen in a long while! According to the links at the top this page *IS* the Garmin Express forum. Could you be a bit more specific?
Do a search on the Garmin Express forum. This has come up and been answered many times before. The short answer is that Garmin Express stores your files in a different place than ANT+ Agent did, so you have to use the new place rather than the old one (simplest thing to do is to make an alias so that the Express folder shows up where the old ANT+ Agent folder did in your ~/Library/Application Support folder). Strava also has a great deal of information on their blog on what's happening and what to do.
