I got the halo 2 multiplayer map pack disc and I'm trying to load it. I got some error stating "no definition file" and had a path of B:\xxxxxxxxx after it....I'm wondering if anyone else has seen this and what the fix is for it. It happened on both my xboxes, but then the disc finally loaded on the one after playing through the first 2 levels of halo 2, saving, and then loading the map disc again. I tried playing through a couple levels on my other xbox and saving, but it still won't boot the halo 2 map disc. The disc is an original and there's no scratches/brand new. This sucks.
