Everytime I try to play the first Mass Effect, it says Disc Error (code: 80010514). The game has worked before and I haven't really taken it out of the case for a while. The disc looks fine on the back, it did this a week ago for Dishonored, but I just got a new disc and it worked fine, but I never played Dishonored, unlike Mass Effect.
Is it the system? Or should I just get a new disc?
