sorry I might not understand your question, just delete the files that are not base game. Or revalidate steam files if you are on steam.
I think the problem may have been solved by the person above me's question, it sounds like the same kind of issues I'd been having.
Also: the decrypter linked has a broken link, so I used Petschko's decrypter.
Edit: used the 1.06 installer and am greeted with this image on startup.
edit2: enabled bbgirl and better saves and neither seem to take effect ingame
