problem:stream output from vertex shader(not geometry shader)

so i was developing a physics system, then i feel the necesity to acces the gpu memory from the shaders to change the vertex buffer fast after moving an object, so i started searching and i find the stream output step in the shaders, so i incorporated this step in my program, modifiying the step because i am still not using the geometry shader as the title of this topic says,i writted all the lines of codes required to do this correctly, the problem came when i runned it in debug mode, the program wasnt going further than the D3DX10CreateEffectFromFile(), it wasnt reading my .fx file, so i started searching for the promen and then i realize that when i added the line: VertexShader vss = CompileShader( vs_4_0, VS2() ); the D3DX10CreateEffectFromFile() wont read the file, so i want someone to tell me whats the problem, is it a library? what i am missing, the libraries i am using are these: #include <windows.h> #include <d3d10.h> #include <d3dx10.h> #include "resource.h" #include <dinput.h> i am not using DXUT i know the advanceParticles sample from the SDK uses this line and the sample works when i run it from there. So what i am doing at the end of the .fx file just to prove that that line isnt working is this: VertexShader vss = CompileShader( vs_4_0, VS2() ); ---> this is the line that makes the file unreadable technique10 Pa { pass P0 { SetVertexShader( vss ) ); SetGeometryShader( NULL ); SetPixelShader( CompileShader( ps_4_0, PS2() ) ); } } And what i am finally wanting to do is this: VertexShader vss = CompileShader( vs_4_0, VS2() ); ---> this is the line that makes the file unreadable GeometryShader gss= ConstructGSWithSO( vss, "POSITION.xyz; COLOR.xyzw;VEL.xyz;MASS.x" ); technique10 Pa { pass P0 { SetVertexShader( vss ) ); SetGeometryShader( gss ); SetPixelShader( CompileShader( ps_4_0, PS2() ) ); } } but without that first line working this final code wouldnt work.
