i installed halo one on windows xp sp2 with a qaulifiying video card (geforce mx 4000).  i installed halo and then got all updates needed for the game.  i start the game and the grapics are totally messed up.  when i play the game i cant see other people.  i cant see the gun i am holding or anything like that.  i have never had this problem before.  i am using the latest nvidia drivers as well.
