I'm having a similar problem, I have created a document so I know they were there at one point, now the only window I have open is the document itself and the 'Pathfinder'.
So I am suddenly missing nearly ALL plug-ins!
I have phoned support and they say I need to re-install from scratch, the problem with this is that the base Adobe package was installed over 7 years ago when Macs ran on 10.2 or something ancient like that. Since then we have only been using different upgrade packages.
(It seems to be a challenge to explain this to them)
HELP!! (Before I loose my job)
