Garmin express(4.0.20.0) does not connect with my FR70. I get the error "FR70 Serial Number: This device is not compatible with Express". I contacted support and throughly uninstall garmin ant plus everything garmin as well as removing any references to garmin ant in the registry. Reinstalled Garmin express error is still the same. I then did a factory reset on fr70 losing a months worth of workouts. Result is still the same. I install Garmin express on a machine that I had never install ant on and the result is still the same. I'm really regetting I bought a Garmin. :(
