Hey, thats great, gonna add that one to my trouble shooting list.
They need people like you as tech support at Activision, anytime I contacted them about any error message, they sent me some canned answer like, "make sure your computer has a graphics card" or "is your game installed?"
I appriciate your dilligence, I am sure it comes from hours of changing one thing at a time and seeing what it does to your game.
