Need help to run Warcraft3 Frozen Throne with 3d-Analyze v2.36. After click "run", got an error message "Warcraft III was unable to initialize DirectX. Please ensure you have DirectX8.1 or newer installed and that your display drivers are current..."

Tried to install DirectX8.1 and figured my OS already has that or a newer version. Every site I googled says 3d-Analyze can run Warcraft3 (it's a 7yr old RTS game, does not use pixel shader. Minimum graphic requirement:8MB 3D video card (TNT, i810, Voodoo 3, Rage 128 equivalent or better) with DirectX 8.1 support.), but no config info anywhere. BTW, the game is installed correctly, as I can use opengl to run it, just too slow to play.

System:
WinXP-sp3
Opteron144-overclocked to 2.7G
DFI Lanparty nForce4 ultraD - socket 939
2GB Ram-DDR400
500GB SATA Seagate
Video card: Cirrus Logic 5446 PCI 1MB. This is the only card I can find after EVGA 6600gt died after 5yr of use.

Thanks and wishes everyone get a new video card for Christmas. ^_&
