Hi, I can does this for you however I would need the complete project source in order to test it, on the link it appears to only have one source file, I need the
"BalloonGameTutorialAppDelegate.h", "Game.h", "FacebookScorer.h",
"Appirater.h"
The best practice is to award the project first before anyone starts work otherwise people may waste time doing work someone else might have done already or you could just take the fix without awarding...
But award me the project and I'll be happy to do this, and will need complete project source to fix it for to work on 5.0
