Try to uncomment the
#define SDSF_IGNORE_COMPILED

If that does not help, I wonder if it is related to the "missing" vertex shader which maybe does not use shadermodel 3.0, but I guess that we would have had more problems in the past with AMD cards then.
Is your directx up to date and your graphics driver?

In pp_fxaa3.c you can also try to comment out line 45 to 47 to see if you still don´t see anything then. If you don´t, open pp_fxaa3_luma.fx and set the shadermodel to 2.0 and see if you see something then.
