App stuck on splash screen. Exception on applicationDidFinishLaunching. Xcode 4.5 and Unity 3.5.6

Thanks for taking the time to read! I've been all over the internet with no luck so far so I made an account in hopes someone might know the answer.

A mobile app for my company stopped working when the provisioning profiles went out. The project is old (about 2 years ago) and needed to be upgraded to make a new build as it seems to old XCode projects and Xcode 4.5 don't get along.

After upgrading the project runs fine in the editor. However when I try to put on my iPad (4.3 iOS) I get the following issue in Xcode that causes the app to become hung on the splash screen:

The plugins currently on the projects are Etcetera, iTween, ObjectiveJS, and XMLParser.

Any ideas? Somet$$anonymous$$ng that might help that I didn't mention? Any help is greatly appreciated.
