My Halo 3 is not working. Help!?

[kyle t]

For some reason I cannot play Halo 3 because whenever I try to play campaign or make a local match it doesn't load. Can someone help?

try buying disk cleaner and clean your disk thoroughly... If that doesnt work you may need to just buy a new game.

maybe you're not logging on correctly or something. if it still doesn't work after you take your time logging on, go to Game Stop and see what the people there know.
