Uploading from multiple Garmins

Hi.

I have a Garmin Forerunner 210 for running and an Edge 305 for cycling.

Any ideas why BT "sees" my 210, but when I click to upload the data, it won't?  It just stays at "0%" and doesn't move.  All of my drivers are current and I can upload both to other desktop and web-based logs just fine.

When I attach my 305, BT "sees" it and uploads the data fine (which is a problem of a different sort - I have been uploading my bike commutes here, which are 2 separate files for the same day - the ride in and the ride home, and it only uploads one and I have to manually insert the other).

Thx.  R
