Simple Vertex Program... not so simple :-(

I''ve setup a super-simple vertex program that just transforms position and passes through light color. Everything gets really dark grey though (like ambient 0.2 light), why could that be?
i dont know the solution to your problem.
but i think you should remove .xyz in the line
MOV o[COL0].xyz, v[COL0];
because its not neccessary.
also you should deactivate all textures beforce using the vertex program, and disable blending.
but i have a question:
how do you get your matrix into the parameter registers?
are you using glTrackMatrix?
i also have a problem with vertex programs, could you take a look at

Yeah, I just put in the .xyz to see if it would make any difference.
I using trackmatrix like this:
And that part works like a charm.

I using trackmatrix like this:
#define VP_C08 8// Map modelview*projection matrix to const c8->c11glTrackMatrixNV( GL_VERTEX_PROGRAM_NV, VP_C08, GL_MODELVIEW_PROJECTION_NV, GL_IDENTITY_NV ); And that part works like a charm.

Just found the problem... :-|
Explicitly disabling both texture units did the trick. I could swear they''re supposed to be off by default!?
