lost bfd/plug ins from Logic Express

this is potentially a stupid question..
I seem to have lost the instrument plugins from Logic Express.
Recently installed LE 7.2 and originally the instrument plugins were there and working.
However I since installed fxpansion BFD and somehow can not see either that or the logic instruments.
I have opened and checked the AU manager and rescanned bfd.
BFD works as a standalone app.
Library/audio/components folder seems to have the au plugins.
The signal processers are all there in the channel insert but not the instruments or the fxpansion application.

any ideas anyone ?
