Bc2000 (for the BCF2000 & BCR2000)

Hello

I'm running ProTools 5.2 (TDM) on a Mac OS9.

Just purchased a BCF2000 and have connected it via MIDI to my Opcode 
Studio4 interface. In OMS I have added the BCF2000.

I can put the BCF2000 into BabyHUI mode. The MIDI In light on the BCF 
lights up, I can see MIDI activity on "MIDI OUT" showing the activity 
being sent to the BCF2000.

In ProTools I have added the BCF as a "HUI" in the MIDI Controllers 
section. However ProTools says it cannot communicate with the "HUI"

I'm all out of troubleshooting ideas. 

Any suggestions on what else I should try doing ?
