Sorry if a dumb question. When I launch the game, I was expecting a box asking for my key. But the game is running waiting for my log in. So what do I need to do when I have the physical copy of the game later tonight?
During the install the game will ask you to activate your copy, you'll then be redirected to battle.net and you'll have to enter your cd key and make a gamertag (only for physical copies). Digital purchases will have the cd-key automatically added to their account
