Ok I also was in the club Green screen.
All I did was down load the original addons and then moved them onto the the proper folders, not copy and paste it, seemed to work.
yes there is a DX 9.0b issue with the 5600 256 cards but who will fix? probably Microsoft since they make the DX program, thats why codemasters isnt responding to some of the emails I sent.
But I'm only speculating.
