Basically MW2 will not start while I am signed in. The weird part is it is only while I am signed in. If I sign out the game loads up fine and I can play Spec. Ops and Campaign but if i try to play Online it makes me sign in and when I sign in it will kick me back to the XMB right away. I'm starting to get really annoyed because it seems like I'm the only person to ever have this problem... I tried a couple solutions myself. I tried deleting the patch and running patchblocker while signed in and starting up but I was still sent back to the XMB right away. The disc itself maybe has one or two scratches but they aren't even bad. Also, it doesn't do this with any other game.
