App Manager 10.0 hangs at "Sign in" with CS6
I am running High Sierra on a new Macbook Pro.
I have downloaded and installed CS6 Design Standard.
As the installation finishes the App Manager pops up and asks for my serial number. I give it and it is verified.
Then the App Manager says that I need to sign in, and when I click sign in the App Manager just hangs and spins.
I have updated the App Manager to 10.0 from the Support Center's recommendation but it doesn't seemed to have helped.

Thank you for your help.
