The experience score is unrated
That's your problem.
DWM will not run unless you have a Windows Experience Index Graphics score of 2.0 or better for your video card. No score is the same as a low score.

If you update your score and it is 2 or above, you should have no problems running dreams. (You should also turn Aero on as it will look a heck of alot better.)
