I downloaded the file youre linking to in your signature, and ran your wdl-script with the nm.fx. No changes made. And everything is just black. Same result on two computers. Also tried using your shader in the above program. But it doesnt work. Well, it does something, since the object isnt being shaded (as it is by default), but it sure isnt normalmapped.

I also tried running the workshop scripts again, but now with the newest version of A7. smoothdemo.c doesnt work - everything is black, except the background which is blue. But both the object and the ground are black. Actually, none of the scripts after normaldemo.c work properly.

I've tried these scripts at a Intel C2D, GF8800GT and a P4 with some Intel gfx. The scripts dont work on any of them.
