Error message: "Your request could not be completed. Adobe Acrobat license has either expired or not been activated.".

I'm getting an error message when trying to create a PDF from Microsoft Excel, stating "Your request could not be completed.  Adobe Acrobat license has either expired or not been activated." but I have an active account.  I can view and edit PDFs using Acrobat Adobe Pro DC when I open other files, I just cannot Save as Adobe PDF or print to Adobe PDF (get same error message).
