Right, I had to get rid of WoW (exams, depressing moment getting rid of it haha) and anyway, I have installed WoW again, installed and upgraded to Burning Crusade, and I have Lich King and Cataclysm waiting. Cataclysm's no issue, but I bought Lich King second hand from a guy who said I believe that the activation key was used..now, it's installing, but when it comes to upgrading on battlenet that's not going to work is it (if it is used)
i don't see any place to purchase only the key, only a place to buy the game for like £30! which is annoying when I have the bloody disc. It might work, bloody hell, but if it doesn't, any advice from anyone would be amazing, thanks a lot!
