I installed Fitness tonight, and it won't work for me. When I start it I see the splash screen for maybe 3 seconds and then it pops back to the home screen. I tried turning it off and on again with no difference. I then tried uninstalling Fitness, went and played some Zoo Tycoon, and then reinstalled Fitness. It is still exhibiting the same problem of silently crashing back to the home screen with no error message. This is the only app I'm having a problem with.
