Cubase 12 instal splash screen frozen on 'checking licenses' for 1 hour!

Just realised I was eligible for a grace period upgrade. Yippee! except the app won’t start…bummer
I don’t see Cubase 12 on the ‘My Steinberg’ eLicenser activation page online
I think I don’t need the dongle any more so does that stack up?
Clearly the new verification process has gone wrong
How do I fix pls

Please restart your computer and make sure that you have the latest version of the Steinberg Activation Manager installed (1.4.11). It should have been automatically installed when you run the Steinberg Download Assistant.
