Played this for a day then I got a system update for my 360. Since then I get a disk error whenever I try to play. However if I sign out of LIVE it works. I've noticed a few other people have been having this problem too, but I, wondering how wide spread this is. I figure if it needs an update, the more people this is effecting the quicker it will get patched. I've tried all the usual fixes(unplug the system, clear the cache, ect)

Yeah I'm getting it too, but I'm getting mine right after the fighting rhino, the next mission going into oscorp throught the induction vent on the roof as soon as I enter it my disk stops reading and I get the error everytime now. It looks like its gonna have to be burned as a full game. My copy is truncated is yours or did you use the ihas to burn it full

I'm having the same problem, 360 version. I'm returning it tomorrow.

My too, but i play until i go to the final stage and i can't do anything!!!

No, but my son and I experienced a hard freeze.
