Shadefiend I too had a similar problem. It mentioned that the activation number should be on the box the game came in, but I found mine on the second last page of the manual, stuck to the notes page at the end. It was in the french version of the manual. I am Canadian so by law everything has to be printed in both languages. Try looking through the manual you might have gotten a game that was produced on a Friday afternoon and everyone was in a hurry to go home
