I am a 57 year old gamer after many years away from video games. I bought a used copy of Forza 4 in great shape and in the game manual it says put disc 1 in and on the main menu choose " Install Disc 2 " When prompted, eject 1 and insert 2. Download disc 2 now or you can download later. I tried with the controller and also tried with the Kinect. I can not find nor do I see such screens or prompts? Please help!
