I have two xbox 360's that I hooked together with a networking cable. I have two copies of Left 4 dead, but one of those copies is the "Game of the Year Edition." When I try to join a game it tells me that I need to get an update for one of the games (presumabley the regular edition) from xbox live, but I'm unable to connect either of my xbox's to the internet. Can I somehow download the game update on my computer and install it one one or both of my xboxes? Or is there any other way I will be able to do mulit-player with these two sort-of-the-same, but not *exactly* the same game?
