Yeah so I am trying Windows 7 and am very happy with it so far but, my version of fallout 3 that i had on a 2nd drive would not work properly so i had to re-install fallout. When i decided to go on live and re-link the game to my GFW live acct its asking me for the games reg key. i can't find the orig box or manuel. I registered the game with GFW when i got the game several months ago and linked it to my xbox live gamertag i have the achv for completeing the entire game and was on my 3rd play-thru. I purchased and downloaded both The Pitt and Operation Anchorage, but since i re-installed the game i need a new key to link it back to my acct. i really don't want to have to buy fallout and the 2 dlc paks again.
if you lost the key you will have to contact bethsoft for replacement
