ah! i had the same problem. i can totally help you! okay, it took me about an hour and several cusses to figure it out.. and when i figured it out i felt really stupid. you just have to register the game on steam. because right now, steam's not recognizing that you even bought the game. in the "games" option, you should click on "activate a product on steam" and then follow the directions. hope i helped!!
+rep me if i was helpful
