I've been trying to get halo 1 for the PC on my memory stick but whenever i try to use it it says the product key is invalid. It also says they recommend reinstalling the game. i have installed it and reinstalled as my memory sitck as the direct installer drive. i'm just wondering if it is possible to have it on your memory stick and use it whever you go wtihout the disk. I already have the patch so i don't need the disk but it still doesn't work on the memory stick. Any advice?
