Help MS FS04 won't load directx 9.0

Please help. I just installed MS Flight Simulator 2004,
but the Direct X 9.0 will not load. I get the message
"The software you installed has not passed Windows Logo
testing to verify its compatiblilty with Windows XP."

I have read that the Cryptographic Services need to be
turned on and running, and mine are.

My System:

Hewlett-Packard Pavillion 520c, Amd Athalon XP 1600+,
1.4 GHz, 512MB sdram, 60GB HD, Windows XP Home edition,
VIA S3 Pro Savage4 video.

Any help would be GREATLY APPRECIATED.

Thanks, Dolby
