Ok, so what happened is that after I loaded up the creation kit and figured out a way to get all the master files working at the same time, the render window would always go black when I selected something. So I deleted all the creation kit related files on SSE and assumed that bethesda.net would allow me to reinstall the files so I could start again, something I am used to doing as I am a noob modder who has no idea what I'm doing. The reason for the render window going black as I realized after deleting the files, was almost definitely because when I was editing the kit to allow all the master files I messed something else up as I was editing values and very possibly edited something I didn't mean to. So now I don't have the creation kit and am not sure what to do as I really want it but have no idea what to do. All help will be appreciated.
