Returning to the World Where Warcraft is Supreme
After thinking about it, I have decided to come back to World of Warcraft, and have decided to get myself a new computer as well. I also created myself a new account because I want to start over. I left World of Warcraft after the first month or so of Cataclysm. I have to redownload the game and game client, and I bought the game before and I have the authentication keys for Burning Crusade, and Cataclysm. But unfortunately I am unable to find the authentication keys for Wrath of the Lich King, and original World of Warcraft (not sure if you need one for the original or not). What should I do? Becuase I rather not have to buy an exspansion set that I already bought once. I would appriciate any help, and advice for past players of World of Warcraft who are coming back to play.
