Okay, I bought this amazing game 2 weeks ago from SDC and I also payed to have a box copy sent to me by Stardock as well. (So I bought the instant download and retail box at the same place, at the same time, as a combo set.)I  recieved a serial key in their email and I registered. Then, today, as I was looking at my box, I realize that the Serial Key I regestered the game with and got in the email is different than the one in the retail box. Did I just get an ultra cheap copy of the same game, or did Stardock mess up?
