I've just bought world of warcraft wotlk collectors edition on gumtree and just noticed the key says - us.
When I entered it on battle.net it says "The authentication key you entered cannot be claimed. Please try again." as opposed to "The authentication key you entered has already been claimed."
So I think it hasn't been used its just on the US server :@ has anybody got a used us wotlk or original key that I can enter in to battle.net to test please?
Also does anybody know if I rang blizzard would they be able to do anything for me as long as the key isn't registered?
UPDATE: Just got off the phone with blizzard who have said they are destroying the old us key and will send me a EU key within the next 24 hours! Not bad for £20!
UPDATE2: New key recieved, entered on battle.net, key accepted! Will get my in-game pet when I next log in! :D
