I didn't make it!
Somehow my TES oblivion construction set got uninstalled and I just got it back after about a month. I cant figure out how to start working on my mod again. I know I have to open the data for the Oblivion.esm and my mod file but I cant remember which is the active file. I've tried both but I cant seem to be able to use the render window at all.
Go into view and activate render window.
