Topic: HDSP mixer v3.26 midi control stopped working with MC Control

I recently had to rebuild my PC and intstalled the latest version of HDSP mixer v3.26. I am on Windows7 64bit with a 9632 card.
I am unable to control the mixer via MIDI with my Euphonix MC Control. In fact the MC control does not populate the track window with the HDSP mixer channels, like it does not recognize the mixer as an APP.
The older version of HDSP mixer worked fine with the MC Control.
All the settings seem to be set the same as before. The HDSP preferences see all the Euphonix EUMidi channels.
Is there something I am missing?
