I have the same issue with an FR70. I contacted Garmin support and their reply was that the FR70 isn't compatible with GE and the problem will be resolved with further updates to GE.
I am now running GE 3.2.13.0 and the issue has not been resolved.
AFAIK the FR70 is indeed compatible.
Try the steps in this FAQ http://support.garmin.com/support/searchSupport/simpleCase.htm?caseId={600f3dd0-3e6a-11dd-d7af-000000000000}&kbName=garmin and also here http://support.garmin.com/support/searchSupport/simpleCase.htm?caseId={8a5f1480-ddf1-11e2-7dd9-000000000000}&kbName=garmin if you've updated Express recently.

There was a posting on our internal network on Friday that said the FR70 issue was in the process of being resolved. I work Sunday - Thursday so this is the first chance I've had to message you. Glad your up an running..
