Yep, same as everyone else in this thread. Bought the game to have some extra tunes since I knew my group and I would be playing quite a bit and now I've got nothing. I figured since the site was finally up, it was safe to put in the code. Guess not. I've already sent an e-mail with my receipt and game code.
I can completely understand not keeping the receipt. Keeping the code to get a code is logically all you'd need. I'm sure if I didn't just buy the game yesterday, I wouldn't have it either.
Needless to say, this whole experience has been disheartening. I don't buy games to be frustrated, yet here we are.
