Cubase 5 plugsins don't work under 10.8.2

Hey is there an update for some Cubase 5 Mac plugins like MONOLOGUE??
That and another one won’t load under 10.8.2 which is crap as I updated my system now can’t use them.
Using version 5.5.3.651
thank you!

PPC?

NB is right… unless these older plugins have been updated to run on Intel Macs, the most recent Mac OS on which they can run is OS X 10.6.8.
