Game Center authentication error – Stack Overflow

I ran into this today and fortunately found this solution pretty quick (below). Thanks Stack Overflow!

In iOS 4.2 when a user cancels the login to Game Center, after 3 attempts that error is returned. You can resolve the error by logging in using the Game Center app, then try your app again, you should see the welcome back message from Game Center in your app
