Tried to login to 2019.  Face a blank screen where there had been "login"  "passwrod" 

Years ago I remember this had to do with Internet Explorer being used as a conduit for the login screen so I thought I would update IE.  Instead I am led to "Edge."  Still can't login.

What to do?  Who to call?  Force install does not work.  Does not recognize me as administrator even though I am the only user.
