It's very possible that the app needs to be updated. With each update of iOS comes internal changes to how processes are called internally, new methods are implemented, etc. Sometimes, those internal changes alter the way apps work (or don't work), and the only fix is for the developer to update the app. BTW, that's REALLY the purpose of the iOS developer beta releases.
