I didn't watch the whole video tutorial until it was too late and had already installed the code patch outside of the installation directory, and I just kinda got frustrated and said to hell with it and tried to start up Morrowind and this is the error message I got "the application failed to start because d3dx9_40.dll was not found." It went on to say that uninstalling and installing the game could fix this. SO if someone could either help me fix this by removing and reinstalling Overhaul or tell me how to uninstall MWGOTY without laying my save games to waste I'd really appreciate it. Just whatever will fix this and allow me to get Overhaul goin right would be splendid.

Apply the step involving installing Directx 9.
