How do I activate 13 pro after trial expired nothing working

Trial expired hit buy now then I purchased , updated to latest version and trying to start cubase and says no licence, try to run activation manager and nothing happens , why is this so hard it should be automatic as soon as I purchased .

Have you downloaded the latest version of Steinberg Activation Manager? What happens when you run it?

Figured it out and got it working, what a ferris wheel it was.
Thanks for responding.
