Beta Update strangeness

Version 1

    When I opened Muse 2.0 just now I was told there is an update. So i went through the update process with no problems, until I received the notice to sign in. Then i repeatedly received the following error message Muse Update Error.png

     

    After a half dozen retries with the same error message I cancelled out. So what is the problem here, and why do I have to sign in?

     

    Then i opened Museto see if the update worked. Here is the About Muse panel

    Is this the latest update?
