ok, this is really starting to piss me off. its not that any of my games are scratched, all my games freeze, including my brand new ones. when ever im playing GOW on live, it'll freeze every now and then, and then i feel like throwing my controller across the room. i was playing splinter cell D.A, and it froze right in the middle of the saving process, and now my save file is corrupted. how do i fix this. i dont know if my warranty is still valid. and i tried xbox.com, but i have to register it, and can only be done for US. should i just call microsoft? i dont trust e-mailing them because they said they would e-mail me back, and ive been waiting 4 months with no response. any helP?
