E-Sign not working

Hi. Please can you help. I've just changed to a new machine and reinstalled Adobe Acrobat. When I log in, it's not showing any of my previous documents, and e-sign is not working at all. All  I get is the rotating wheels shown below - and it never moves on. I've tried logging out / logging in, rebooting routers, removing and reinstalling. None of it works. I can still access the functionality and files via the web portal, and also on my old machine, on the same network. Help! Thank you..
