well fuck sake. Apparently i can't play the full game, because when i first got it, i obviously used the cd key. well that was a long time ago. I'm pretty sure my old battle.net account somehow got lost or whatever, but i ended up having to make a new one, with the same email address. My game is not in the list of my activated games, so even though i don't have an account using that cd key, i still can't use it again. >.>
