OK. So this is what's been happening. I went on MW3 on the PS3 and everything was working fine until... I got in a lobby. My sound shut off. I didn't realize this at first but then when I was playing the game I realized the only sounds I heard where the bullets. So I restarted my PS3 and tried it again but this time when I entered a lobby the sound turned on and right when the game was about to launch my console froze. I cleaned the disk and the exact same thing happened. I then took the game to gamestop and the man said that it could just be a "bad update download". What ever that means. So he told me to try it at my friends house and if it worked there then the problem was the "bad update download". So I went to my friends house and tried the disk and it worked perfectly. I don't know what to do and there hasn't been a new update for over a month. I have tried over and over again to get the disk to work and i even re downloaded the update. i was thinking I should try to re-download a patch but that would take away my DLC. I was hoping that this has happened to someone else and maybe I could get a solution. Anyone want to help?
