Yesterday, I was hosting on CoD4 bypass. Then when I stopped bypassing and went to play normally, as soon as I clicked on Multiplayer, it automatically quit to the main PSN menu. It did it again when I restarted my system, and then I tried Mw2, and it's the exact same problem. The weird thing is, that Black Ops and Mw3 work perfectly fine. I even tried the discs on my other Ps3 and they wouldn't load, and the problem only occurs when I'm signed in. I had friends try to play on my accounts and they can play just fine. I made sure the discs were clean & even got my cousin's discs and they didn't work either. If anyone knows how to fix this, please respond, I've tried almost everything and I'm really desperate for answers.
Thanks.
