Hi can anyone help me, my crysis2 online doesnt work anymore I really dont know why, but the problem is that whenever I clicked the multiplayer mode, it will load but when the "checking privilages" my ps3 resets, it goes back to the ps3 home screen. Then if I try it again it will happen again sometimes it will just make my screen black and my ps3 is already hang

Pls can someone help me pls!
