Dave Smith Instruments SYNTHESIZERS

OK, I just can't seem to get the PolyEvolver editor to work. I have stripped my system down 
to a TiBook G4, a Midisport UNO (1x1) midi interface, and the Poly. Everything works and 
tests OK in AudioMidi Setup. I have the latest version of the PolyEditor (1.1), and I am 
getting NOTHING. Can't send programs into the Mac. I can't even "poll" the poly, I get "no 
communication." Can't get the "midi piano" to do anything. I have checked connections, 
etc.

Has anybody had any success in getting this software to work with Mac
OS X? Any help would be greatly appreciated.
