Try clearing your cache

Instructions are at E How under

How to clear your cache on xbox360

I've tried clearing my cache, i even formatted my hard drive

There are two ways to clear the cache, one is holding one of the buttons, not sure which one, I think A, until the game EA logo appears.

And the other is a X - X - RB - LB - X - X routine in the proper menu. Make sure to try both.

Let us know how it turns out.

P.S. Cache memory and hard drive memory are different.

And of course try unplugging the unit for 10 secs as well.
