Stupid question time, Miranda -- are these 40 library FX the same as the "Legacy" folder I see in my Particles? I see Super Tools, and I see the Legacy folder which has sub-folders like "Atmosphere", Environment, Fire and Smoke, Text" etc. But I don't see any Library that has only four folders/categories like you are describing.
Edit: Nevermind, a reinstall and now I see those four folders (under the Library 40).
The "Legacy" folder contains all of the original/old FX.
