Hope it's okay to ask for tech help here . Xbox 360 - first time since I got the Game of the Year edition that I was going to try out mutilplayer , game prompted me to put the 2nd disk in ( disk has Undead nightmare and multiplayer ) and I just get a black screen . Can call up the Xbox button menu anytime , restart , try to jump in straight onto the 2nd disk, no dice . FYI I bought this used . I've owned a previous copy of RDR , on disk , with Undead Nightmare as a downloaded DLC, but I deleted this before installing the GOTY disc onto my 360 Hard Disk . Help !
