Demo - unusual graphics problem

[Drumsfellow]

I've tried this, but I can't seem to get it to work.

I've downloaded MSXML 6.0, but it won't install on my computer cause it says there's already an existing version of the program. When I try to delete that in Add or Remove Programs (it's listed as "MSXML 6 Service Pack 2 (KB954459)"), I get an error saying "Fatal error during installation." :/

I already have .net framework installed, so I don't think that's the problem.

I've tried using the program (Mobility Modder) anyway, but it doesn't do anything--the drivers won't install, just like before.
