I just upgraded to the latest version of 21 Pro: Blackjack (version 1.0.3) and the game has suddenly stopped working on my iPhone. I have: 1) Installed the application from both the App Store and iTunes. 2) Run the application multiple times. 3) Restarted the phone and run the application multiple times again. 4) Uninstalled and reinstalled the application from both the App Store and iTunes. Nothing has fixed the problem. Every time, the game simply crashes back to the home screen. My brother has a non-jailbroken iPhone, and I tested the new version on his phone and it works perfectly. Any idea what might be causing this?
