About a year ago, I decided to play New Vegas again after not playing it for a long time. I started a new campaign. I got to prim and went in the casino and the man talked to me, but when the conversation was over my 360 said the disc is unreadable. So i cleaned it tried it again, same ting happened I then tried just skipping the quests in prim. When I got to the area where you help the ghouls go to space the ground wasn't there and neither where the stairs to get into the building. After that I went to my other save where I had beaten the game and I was getting the same issues through out the game. I even went out and bought a brand new game and it was still happening. Then I tried deleting everything off my xbox that had to do with New Vegas, it was still happening with both discs. I just gave up. Resonantly though, I got a brand new 360 and tried playing it again, but it is still happening! What is going on? Can I fix it? Is it my xbox profiles problem? Or am I just completely boned?

Thank you.
