Dave Smith Instruments SYNTHESIZERS

Hi,

Is there any Mac user out there with Evolver successfully installed new 
OS.2.0?
I need help, I have mac OSX and OS9.2.1. I have tried using 'SysEx 
Librarian'
Evolver begins to quickly count down from 31 gets to 30 then flashes 
cryptic display [-7-] and stops.
meanwhile 'SysEx Librarian' continues to send message. The end result = 
  I still have OS1.1
If there is a way around this problem or another utility that works 
(OSX or OS9)
please let me know. I have no extraneous MIDI data being transmitted 
from other device(s),
and cannot find a way to adjust size and number of output buffers.
(not in 'Audio MIDI Setup' utility in OSX anyway).
Any help would be gratefully appreciated!

my connections:-

Mac OSX > SysEx Librarian > USB > Edirol UA-20 MIDI Out > Evolver MIDI 
In.
