Not working on iphone 3g

After adding to the iphone 3g i only get the airplay splash screen followed by a black screen then automaticaly exites. Any help?

ok change that it works after i restarted iphone but it doesnt exit once i press the X.

I think it not exiting is a known problem, I think it is written up in one of Win32 forum.

Here is the link about not exiting when pressing the X:
