i recently tried to play fallout on the 360 and was told there were expansions available. i install them and it then opens the cd then after it reloads says that i need to update for the expansions to work so i do that and then again reloads and goes back to there are extensions available. no matter how many times i do this its the same result and i am now unable to back out or play the game. is anyone else having this issue or know what i should do?
