I have XP service pack 2 dxdiag ahows that i have directx 9.0c but when i try to run World of Warcraft i get the following error messege: World of Warcraft was unable to start up 3D acceleration. Please make sure Directx 9.0c is installed and your video drivers are up-to-date.

do the diagnositc thingy - run>dxdiag>display>test

Howdy y'all,

I'm having trouble installing Dx9. I have Win XP, and SP2, and yes, I know SP2 installs Dx9, but I replaced Dx 9 with Dx 8.1 because my games dont like 9, but work perfectly on 8.1. But now..... I want Dx9 back. Is there any way I can do this short of re-installing win??

Just to let you know what I've tried so far (none of these have worked,obviously):

1. Install DirectX 9.0 from the MS site
2. Install SP2
3. Install DirectX 9.0 off game CD


Any help is appreciated,
Thanks.

My setup was fine for the last 2 or 3 months for world of warcraft till just the other day when I eradicated some viruses giving me unrelated problems. Now I get the exact same message you do about no DirectX or video drivers out of date. I went and reloaded my drivers, now I'm trying to figure out how to reload DX9.0c..... annoying.
