hey everyone i has gotten this one patch i guess from an old friend who i havent been able to talk to since his account got banned on xbl and i got it from him over team viewer. i have it still but forget how to use it. i know i have to start a zombie game and end it then use that saved game and put the patch on it but i dont want to screw it up. also i have to delete the update but the patch i have was from last year around like december so idk if it will work. can someone tell me what to do and if it will work. i do have usb xtaf and modio from when i mod my gamer tag. thanks
