Im having problems adding the Nuketwon map dlc on black ops 2. Im on tu 17 (not 18 cause im having problem with that for some reason) Usually i have no problem with dlc. I just put the usb that was used by horizon to trasnfer the dlc and thats it. When i open black ops 2, theres no nuketown map even if i put the usb. Whats funny is, when i unplug the usb with the dlc in it while the game is running, it would stop and say "missing dlc error" so im sure that the game recognized that theres a dlc in there.
