Wondering if anyone can tell me why my stats would be reset.  I was playing split-screen on my PS3, on my little brothers account, and a pop up came saying, "Probation for leaving games early" when we were kicked for somebody else's bad connection!!!  Also, the PS3 is mine.  I'm the one with the head account, I was just playing on his account so he could be top screen.  I would really like an explanation for this, maybe even tell me how I can get my multilayer stats BACK.
