Sound Librarian won't receive prologue

[GeorgeReedRadio]

I installed prologue Sound Librarian onto my iMac. The Mac sees the prologue (it is on the MIDI list). I am connected via USB and using the Mac driver. I ran the Korg driver uninstall program.

When I try to receive data from the prologue, nothing comes over. Instead I get a message to check my MIDI ports. I configured the ports manually, using the recommendations from the manual (and have unsuccessfully tried all combinations).

Suggestions?

Is MIDI Route set to USB, in Global Edit mode?

Are there any other apps on the iMac trying to use MIDI, and causing conflicts?

I tried it both ways in the Global mode. Neither worked.

In addition to the prologue, I have a Kronos, three Quantum interfaces, a Presonus DAW controller and a LaunchKey MIDI controller connected (and showing up as Devices in the MIDI Studio window).
