I installed Garmin Express today and it won't recognise my forerunner 610. I am running the latest Mac OS (updated today). My forerunner was crashing through the day (firstly on a mountain bike ride, then on a run later on) - I did a hard reset and now it can't get the actual time.
I have an ANT+ agent installed, the watch is prone to crashing about every 8 months. The watch is two years old and on 2.90 software.
Thanks
