lost my cd key
so i just bought AC black flag and after activating it, downloading it and going to start the game, a window popped up saying"this is your activation key for the game" which i didnt realize i needed to activate the game on ubisoft. this is the first ubisoft title ive had to do this for so not to mention its the first ubisoft game (other than the division 2) ive ever bought (didnt need a code to get it on ubisoft) i closed the window and now have NO IDEA where to find the activation code to actually go play my game.
