I found a way around this its annoying but it works. First log into the game NOT signed into psn. Second make sure your textures are downloaded to hdd. Third start a local gane and as soon as it starts. 4th click play online and sign into psn and it will work. PLEASE NOTE:if you do this on the multiplayer screen if you switch to zombies it will freeze so close the game and do this process again on the zonbies screen to play zombies and vice versa.
