Those drivers are made for Vista Build 5384.4 which has not been released to the Pbulic yet. So if you are using that one....
There is no guarentee that these drivers will work on older versions of Vista since they are directed toward that build.
So same questions as before. Is your card a DX9 card? Is is supported?

Is it on that list? If not then your card is not supported and most likely will not be able to take full advantage of what Vista has to offer.
