CoD4 Errors...

[Kound93]

I Installed CoD4, It Showed Up, CoD4 Single Icon And CoD4 Multiple Icon On My Desktop. I Clicked One Of Them, And This Showed Up; ----- Initializing Renderer ----
----- Client Initialization Complete -----
Attempting 44 kHz 16 bit [Windows default] sound
----- R_Init -----
Getting Direct3D 9 interface...
Pixel shader version is 2.0
Vertex shader version is 0.0
Video card or driver doesn't accelerate transform and lighting.
Video card or driver doesn't support UBYTE4N vertex data.


Error during initialization:
Video card or driver doesn't support UBYTE4N vertex data.

So I Clicked The Other, And It Showed Up The Same Thing.
Can AnyOne Help Me?
I Have Window XP ( Laptop )
