Fill and Sign not working on Adobe Acrobat Pro DC

I have Adobe Acrobat Pro DC installed and when I select the Fill & Sign option, the following message is displayed on the screen:

logAPI.startLogSession("OneAppIsReady"): https:??ma-resource.acrobat.com/fllsign@font-face {font-family:adobe-clean; src: local("Segoe UI');}@font-face {font-family: adobe-clean; font-weight: bold; src: local('Segoe UI');} logPI.endLogSession("Requiring:main.js"));

I then go back to the document..... Help.
