Halo 3 campaign. Game breaking bug

I am playing halo mcc with no patches which may be the problem. I am on the level Tsavo highway and When you get to the first covenant barrier (big blue wall). I died and then the game goes black and leaves this error. Contact bungie.net. oops something bad happened please do not reboot. This is horrible and i hate it. It was working the night before but today its not and im getting that error. Its is a disk based copy. I am waiting until my bandwidth resets to get the patch so maybe that will fix it. Please Give Me some help.

just don’t contact bungie.net, have you tried updating?

This is some bull I just got that to but I was playing cortana. Then I took the disk out and put it back in and then it worked tell me if it works for you
