Ok. So I've been playing WoW for a while. My sister recently started and for the past 6 days has had a trial account. When she bought the game card to try and upgrade the account it woudln't let her upgrade without a retail authentication code. Can she use the authentication code from my copy of WoW because she is in the same household only on a different computer, and still subscribing to her own personal account, or do we have to go out and buy another copy of the game and have an extra and useless disc floating around?
