How do I correct settings for Collapse Blast to access Facebook? I installed Collapse Blast on my iPhone 4 and I can't log in to play. I get an error message that the game can't access Facebook and to change it in settings.

I have changed everything, uninstalled and reinstalled and still won't work.
