I have never in my life seen such horrible support for a game. Who would think in this day and age. The game wont even run on my system. Brand new computer , installed it twice from Steam. Different drives, Win7 X64 Home, i5 , 6GB DDR3, nVidia 460 GTX. I have normal hardware, fresh OS, Fresh Steam install. Install the game, go to run it and nothing happens at all, just a pop up that says its about to start ,, then nothing. What a POS. All my other games (35 of them) run fine. This game is dog****, I wont my money back.
My first guess is 64 bit. Can't you start COJ in compatibilitymode? or 32 bit mode?
