I bought an xbox360 that came with a download code for Halo Reach about a year ago. It worked good for quite a while, and then in the past few months while I’m playing with friends its fine but once the game ends and goes to the credits, a screen will pop up saying Disc error and take me back to the dashboard. Now I’ve tried deleting it from my system and redownloading it and re-installing it several times and it still happens. I asked a Xbox support tech and he just told me to check the forums. It’s getting annoying.
