EXS 24 Logic Sampler Users Group

Hi,

I've been away from the EXS24 for over 6 months and recently I'm having a terrible time 
trying to use it.
I've read the LP7 reference and plug in reference manuals and cannot locate the EXS24 on my 
G4 dual nor can I open it.
Previously I had no trouble and I was able to open the sampler and load and edit the factory 
samples as well as some 3rd party sounds.
When I click on the "inserts" word in the audio track mixer the EXS24 does not appear nor do 
the 3rd party sounds.
I'm using LP7.2
Any ideas how I can boot the EXS24 and call up sounds?

Thanks for any help,
Regards,
Jim
