I am having the same issue. First gen MCU, with 2 extenders (all on version 2.1.2), Motu midi express XT, 002 Rack, etc. It worked fine for me when i was on PT LE 7.4 and win XP 32 bit. I have recently upgraded to Win 7 32 bit and PT LE 8.01 and started getting the same message. It works for the first 7 seconds and then the message pops up.. Unable to communicate with HUI... I can then hit enter and it will work for another 7 seconds, which tells me its probably not getting that midi signal back? Have you fixed this or have any leads?
