Need help on access violation error

I am getting an access violation in D3D8.dll:

D3DX: (INFO) Using 3DNow Instructions
First-chance exception in VertexShader.exe (D3D8.DLL): 0xC0000005: Access Violation.
The program ''C:\Program Files\Microsoft Visual Studio\MyProjects\View\Debug\VertexShader.exe'' has exited with code 0 (0x0).
on this line of code:
pd3dDevice->DrawPrimitive(D3DPT_TRIANGLEFAN, 0, sector[sec].polygon[poly].numverticies-2 )
as well as any other DrawPrimitves.
How can I fix this?
Thanks...

I would assume so.
These commands work fine:
pd3dDevice->SetStreamSource( 0, sector[sec].polygon[poly].vertbuf, sizeof(LEVELVERTEX) );
m_pd3dDevice->CreateVertexBuffer
m_pd3dDevice->SetTransform( D3DTS_VIEW, &m_matView );
and others.
This is unless there is something else when it comes to DrawPimitive calls.

m_pd3dDevice <---> pd3dDevice
????
Are these two something different? That would explain it...

Could you please post your entire render code? Have you verified that your numVertices value is correct?

Are you aware DrawPrimitive takes the number of *polys* instead of vertices? That might cause the access violation.
