Ok guys so ive been playing all day i get an update and pow... freezing. So i deleted the last update, then re-downloaded the file. Right when i loaded it up i thought it might freeze so quickly i ejected my disk and safely went back to DB. I continued to try by loading the game a second time, this time tho i qucikly before it froze up started up a local only game, went into the lobby no issues backed out and then loaded mutliplayer up fine =]

Hope this works because i know this issue is annoying when all you want is to kick zombie @$$!!!! Sry if it doesn't i tried =/
