"MW3 content required. DLC content is required. Piazza is missing or damaged. Gain access by purchasing a map pack"I recently download the DLC and it's not working, i'm premium and founder too, what's happening?
I already own the DLC，I played the DLC。（MW3 PC） HELP!!!!!!!!!!!
verify the game cache, install/update singler player, that should work, or go into your MW3 Folder and delete "zones" folder and will trigger an update.
