Lightroom in Adobe Photoshop Photography Program

I had downloaded a "trial" version of Lightrrom 5 which was expiring. I elected to subscribe to the Adode Phototshop Photograpy program in CC.  The account was establised and I downloaded Photoshop with no problem (as well as Bridge).  Ther was no option for Lightroom.  When I go to open the already downloaded version of Lightroon it asks for a purchased serial number.  When I look at the apps tab in the download installer it shows Lightroom as being up to date but not as being downloaded under the home tab.  Any ideas as to how to access Lightroom?  I am running OS X 10.9.1
