Adobe Sign for Word Addin Dialog Box does not show - blank screen

Hi,

After selecting "Send for Signature" for a Word document and clicking "CONTINUE" a blank screen opens up and nothing happens. Normally this screen displays the Word docx in PDF format and allows for adding signatures.

Several Windows 10 users in our company report the same problem with the Adobe Sign Addin for Word.

What's up Adobe?  This has been happening (or not happening) for weeks now.
