The qn genuine or
pr@ted has nothin to do here. Seems like some incopatibility b/w display driver files nd DX files.
Dirst get the lates display driver, nd then install latest DX 9.0c like the Nov update of DX 9.0c for XP.
Maybe uve the older versions of 9.0c as MS releses updates for it every 2 or 3 months and most games needs the latest one to get workin.
If this doesn't work, u can try DX9 removal tools to completely remove DX files nd then u can freshly install DX 9.0c latest.
