setting up eastwest symphonic choir in logic 9

I have installed Logic Pro 9 and Eastwest Symphonic Choir (Play) (EWSC) on my new iMac. Logic does not "see" the EWSC Play when I try to chose Play for a new Track and Instrument. How is this done? It is not the same as setting up the EWSC in Logic 8.

The steps please?

Thanks!
