Can't find Dimension Pro in Logic

I installed dimension pro and the 1.5 update patch....but when I open Logic Express 9 I can't seem to find Dimension anywhere. I have never used it so I don't really know where to look but from what I've read it should be in the instrument library with all the other instruments. Its checked and sucessfully validated according to the Audio Units Manager in logic.. so I'm not sure how to get this thing working.
