I have a mod for halo 2, which changes all the maps and guns etc. etc. But when i try to load a map the screen goes blank and it goes back to the pregame lobby, does anybody have any ideas what this could be?
If you downloaded it then probably your problem is that they screwed up while making it or something. This wouldn't be your fault unless you tryed editing something yourself or applying more than one patch to a map or apply the patch to the wrong map!
