For some reason im having a hard time playing Halo:Reach multiplayer with my party. Each the the match is about to begin, an error message pops up saying the disc is unreadable, and automatically boots me from the match. The rest of my party stays in though. However, if i play it solo, the disc error does not come up. Im able to play the match with no problems. What gives? Im baffled by this. Is this a recent glitch? I have never had this problem before, and to make matters worse, Bungie sent a message saying im quitting too many matches!!! What do I do?
