Product keys
Hey,
My brother bought Battlefield 3 yesterday and since it is an awsome game i thought lets install it on my own pc, when i found out that you need a retarded product key so i asked my brother and he said: "oh yea its over here" so i used it and now it says: 'this code is already used'. So my question is: Can you only use the product key once? if yes: where can i get a product key to install the game? if no: what do i do wrong?
