Embracer and Monologue missing

I have Mac OSX 10.6.8 and Cubase 6.0.0 and everything works great. When I up-graded to 6.0.5 on Cubase
I lost a number of plug-ins and could not get them back. Had to go back to 6.0.0. I don’t dare up-grade. I’m perfectly content with everything just the way it is now. Why create problems for myself?
Fortunately there are many of you guy’s to help me get back on track. I don’t know what I would do without
all of you.
