Upgrading from CS6 to Dreamweaver CC "up to date" does not allow installation of new product.

I'm trying to upgrade my mac from CS6 to dreamweaver CC, but my adober app manager says my dreamweaver is up to date. I know this is not true because I don't have the insert edge animate project button which the new dreamweaver CC advertises.

How can I install it if my app manager thinks I already have the latest version?
