i cant find my cd key any where its not on the manual or the case plz help!!!!

Game does not have a cd key.

Why does it ask for one, then????
There is a code on the box and it starts with BLZ-, mine does not work however. .

My key is not lost, although it does not work.

are you talking about the online code?
i cant find my code where is it supposed to be and how do i find it?

Yeah, same here. In the onling sign in spot it asks for like a key and i have no idea where or what that is. Is it suppose to come with the game or is that something i should have gotten when i first signed up for an account on UBI.com?
