2017 Draftsight Activation Issue

Apparently this is an ongoing problem (from older posts), but I have today received the dreaded "Welcome to Draftsight" grey activation dialog.  I fill in the appropriate information and tah-da! . . .nothing.

It has been working wonderfully until today.  I go through the dialog box, and am waiting for an email, or message or something.

Any help, please?

 

Thank you in advance.
