I currently have the same issue. bought ds3 from a pawn shop, ten bucks, thought it was a good deal, only i was not aware you needed an online pass to play co-op. now here it is i go to access the online pass and its got some red circle with a line through
it, basically prohibiting me from downloading it. i havent the foggiest what that means...
xXswb34rXx this may mean that either the code has been used or was not at all included, or it may have already expired. You should be able to purchase another online pass from the Xbox Live market place by searching for the game an then viewing all the
available downloadable content for it. Simply purchase and then download it and then restart the game. You should be able to use any online features without further issue.
