Error means that catalyst is not 'seeing' the phoenix cards

double check the driver and download the latest driver from the Active Silicon Website:
http://downloads.activesilicon.com/p...-v05_43_00.dmg

Also double check that you are actually running in 32bit mode
(System profile / Software / 64-bit Kernel and Extensions = NO)

Otherwise, Contact Active Silicon phoenix Support:
phoenix.support@activesilicon.com

and send them your a system profile (not catalyst system profile) for BOTH macs with Phoenix cards installed in both for comparison.

Open system profile via apple menu and about / more info - save as XML / SPX
