Why is my app not working on my Android phone?
The first thing you should try is restarting your phone. If this doesn't work, go into your phones settings and select Applications >>> Manage Applications and tap on the app. From there, select "clear cache" and "clear data." This will reset the app and often helps fix any problem you are encountering.
