Storyline 2: Preview feature and Player settings pop up not working

In Storyline 2, my preview feature will not work when clicking on any of the preview buttons. I get an error message or it fails to load. Further, the Player settings pop up will not appear. 

I have tried uninstalling and reinstalling. That did not work. I have also tried working from a single monitor to see if it was a multiple monitor issue as I saw in other discussion threads, but that did not work either. This is consistent across all of my Storyline projects. Please advise.
