I know 4.04 has been out a while, but I just got around to my first project using it and I have found the following problem:
1. Place a couple of objects in a scene
2. Set each object to a different set
3. Go back to the main Invigorator screen (not options, just by pressing F3 in AE)
4. Select the object icon to rotate the objects
5. Try to select any set (normally says None). It will not select anything, it will just say "none" and won't move any sets.
