Apple Logic Pro /LogicExpress Discussion

Hi

I just upgraded my logic express 7 to 8. I have some garritan
libraries and the motu ethno instrument. When I look in the audio
manager I see all of them listed and validated,but when I open a
project in logic and click on assign and audio units all I see are the
Apple items. How do I get mine to show up there as well?

Thanks

David
