I've owned this game since launch played it for 300 hours plusm Platinum trophy but lately the game is tempermental i either get repeated menu music glitch, or the music stops playing , i also get the spinning ring of death . Just now it froze connecting to multiplayer. When i was on the multiplayer it froze loading a custom game . do i have to buy a new disc nearly 2 years later , and just last night the game was working perfectly . it has no scratches., smudges or anything of the sort so what should i do?
