After getting part of the answer at the Protel discussion group, and part of the answer by experimentation, and part of that answer at "the other place", I finally got it to work.
You have to change 5 bits to 0x90 (NOP) in one place each for the Schematic Editor and the PCB Editor. Then you have to make sure that your libraries are in the root directory (not the Documents folder). Finally, after over a year of work-arounds I have it working. It is all explained on page 3 of the discussion on "the other place":http://www.diyaudio.com/forums/parts/51 ... 9-a-3.html
Hope this helps someone in the same boat!
