Barry,
You can get DirectX 9.0c here
http://www.microsoft.com/windows/directx/default.aspx or here
http://www.microsoft.com/downloads/d...1-914185249413
as for the Nvidia Driver....mine only shows version 71.84 (English) using a special driver hunting program...but as you say the NVidia site shows version 71.89...not sure if this is a different driver or indeed a newer one.
Regards.......Mark
