I had a problem when i tried to run it (could not find d3dx_25.dll or something similar.. i tried to install direct x and got a "not a signed product" without a chance to continue anyway..
then i dloaded the stand alone version of directx.. and when i run that.. it says its updating.. but the update takes a blink of an eye and its done.
the demo doesnt start.. just a black screen that drops me to the desktop as soon as i doubleclick the icon.
can i uninstall directx completely (without an OS reload) and then reinstall directx clean?
