I installed DirectX9.0b few months ago then had Omega Radeon driver
installed (2kXP OMEGA DRIVERS 2.5.67 8-22-04) several weeks ago.

Recently I downloaded 3Dmark05, and this little pop-up windows says:
Direct3DCreate failed.

Uninstalled that and installed Cataylst 4.9. Reinstalled 3dmark05. Same
thing. Tried to fix this by installing DirectX 9.0c (using dxwebsetup). No
go. (pulls hair) I uninstalled 3Dmark05. Now got to reinstall DirectX 9.0c
SDK then install 3dmark05 once again.

Still that darned "Direct3DCreate9 failed." window popup!!
