I'm willing to think you either don't have the HLSL folder containing the .FX file needed for the shader use or you don't have it in a folder where MAME expects.

HLSL should be in the DIFF from mamedev.org.
If you don't have it, it was posted here:

One way to really make sure is to run with -verbose, if there is a message similar to:
Direct3D: Unable to load primary.fx
.. then simply place the folder from the download linked above in the same folder as MAME.
