While taking my Halo 3 disk out of it's case, I accidentally cracked it. Now it won't load most maps. I don't have the money to replace the game. When I try to install to my HDD, I get an error after 1% stating disk is unreadable. Does anyone know of a way that I can download an installed copy of Halo 3 and use XPort to put Halo 3 on my HDD? Any help would be VERY GREATLY appreciated.
