I have opened and worked in my ProSeries for tax year 2020 for almost a month.  I was in the application yesterday.  All of a sudden today, it will not open (don't even get a sign on screen).  I even tried re-installing the application from my CD.  After it said the install was complete, when I clicked on the "Launch ProSerice Now" button, nothing.  No sign on, nothing.  I can go back and run my ProSeries Basic for 2019 but nothing now for 2020.

Thoughts/Ideas.
