For now, I've gone back to firmware 2.8 which was working fine for me. Anyone who has worked through this problem and solved it, feel free to chime in.
I've upgraded to 3.0 and have had no problem uploading Fit data to Garmin Connect.
I've read about other's having problems with the upgrade failing.
I'm developing software that loads ride data from a Fit file. It works fine with the version 2.8 file, but has problems with the 3.0 file. I've started investigating my software and discovered I was improperly handling some data. It was adequate for 2.8 but not 3.0. I suspect Power Agent may have a similar problem.
There is more in the Road Cycling forum, including instructions for how to resolve update problem.
