I tried to convert the shader to HLSL but it doesn't work.... the engine starts and close without a message. => crash?

what's wrong?

here is my prototype shader:

Code:

---

//--------------------------------------------------------------
//                    Texture Projection Shader
//
//                            by zSteam
// -------------------------------------------------------------

float4x4 matWorldViewProj;
float4x4 matMtl;

float4 range = {0.01f, 0.5f, 0.05f, 0.0f};
float tps;

struct VS_OUTPUT
{
	float4 oPos   : POSITION;
	float2 Tex0   : TEXCOORD0;
	float2 Tex1   : TEXCOORD1;
};

VS_OUTPUT mainVS( float4 oPos : POSITION, float2 Tex0 : TEXCOORD0, float2 Tex1 : TEXCOORD1 )
{
	VS_OUTPUT Out = (VS_OUTPUT) 0; 

	Out.oPos = mul(oPos, matWorldViewProj);
				
	tps = mul(oPos, matMtl);
	tps = tps * range.x;
	tps = (tps * range.yyyy) + range.yyyy;
				
	Out.Tex0.xy = tps.xy;
	Out.Tex1.xy = Tex0.xy;

	return Out;
}

texture entSkin1;
texture mtlSkin1;

sampler ColorMapSampler = sampler_state
{
	Texture = <entSkin1>;
	MinFilter = Linear;
	MagFilter = Linear;
	MipFilter = Linear;   
	AddressU  = Clamp; // don't wrap around edges
	AddressV  = Clamp; // don't wrap around edges
};

sampler ProjTex = sampler_state
{
	Texture = <mtlSkin1>;
	MinFilter = Linear;
	MagFilter = Linear;
	MipFilter = Linear;   
	AddressU  = Clamp; // don't wrap around edges
	AddressV  = Clamp; // don't wrap around edges
};

float4 mainPS(float2 Tex : TEXCOORD0) : COLOR
{
	Color = ColorMapSampler * ProjTex;
	return Color;
}

technique projector
{
	pass p0
	{
		zWriteEnable=true;
		VertexShader = compile vs_1_1 mainVS();
		PixelShader = compile ps_1_1 mainPS();
	}
}
