Crashes on all iOS versions before 6.0

Hey ablfx!

I have been testing my application on multiple devices, and have discovered that it crashes throwing the following error on all iOS versions before v6.0 (in specifically I tested v 5.1 and 5.0).

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[GKPlayerInternal setAuthenticateHandler:]: unrecognized selector sent to instance

After googling the issue, I came across this article that indicated that ”authenticateHandler" is iOS 6 and newer only.

Any chance you could update your library to support previous iOS versions as well? If not - any workaround you could direct me to?

Thanks!
