I bought ME 3 for PC back in February via Origin. No problems at all with it until I just felt the desire to revisit one of my all time favorite games. When I went to start the game Origin told me I needed to reenter the product code in order to play the game... down side is.... I cannot find my product code. Is there any way to get a new one?
More details of what exactly doesn't work for you will be needed if you really want help....
