my main render function is the following:

//mptile->Render();
if (mppane)
mppane->Render();
UpdateStats();
mpdev->EndScene();
}
mpdev->Present(NULL, NULL, NULL, NULL);
return D3D_OK;
}
I am loading a 256x256 tga and placing and 0,0.
The damn bitmap is not being rendered on the screen and it''s driving me crazy... HELP!!!!
Any suggestions??
