I have a geForceFX, but as far as I know GF4 support shaders also. I'm not sure of what versions it supports however. I think the problem you are experiencing is that you are using the Directx 8 version of these shaders. As of version 6.31 we now have a directx 9c interface in A6, and the shader needs to be setup slightly different. There is info on this in the update readme. Hope that helps, if not, I dunno...

EDIT:
occording to the wiki, the GF4MX does not support shaders. Only the GO and TI models support them, and even with those cards you can only use vs1.1 and ps1.3. Funny, I thought all GF4 supported shaders.
