I wasn't saying I don't believe you, I'm just confused, because there's nothing I'm aware that could possibly cause that much trouble. And I'm utterly sorry it is not yet working for you.
You do have DirectX installed on the computer that "D3D10CreateDevice" error message came up? Because interesting enough it tries to find the entry point in the game executable, not the DLL and that's something I have never seen before, nor does it make any sense.
