Thanks Steempipe, this part works now!

But the next error lies here:
Code:

---

VertexShader =
		
		asm
		{
			vs.1.1
			
			dcl_position v0
			dcl_normal v3
			dcl_texcoord0 v7
			dcl_texcoord1 v8
			
			m4x4 oPos, v0, c0
			m4x4 r10,v0,c4
			m3x3 r8,v3,c4
			mov oT0, v7
			mov oT1, v7
			mov oT2, v7
			mov oT3, v7
			
			//calculate texture space matrix from normal and up
			mul r0,c31,v3.zxyw //-1,0,0

			mov oD0,r3

		};
	}
}
   ";
}

Downwards the red line several errors coming up:

Please excuse my kind of ignorance, but i have absolutley no knowledge of shaders.
