Can't register CorelDraw 2017


I just installed Corel Draw Graphics Suite 2017 on a Windows 10 computer.  It installs as it should, but then when I get to the registration screen, it says it can't connect to the internet.  Error message shown here:  

I've tried uninstalling and reinstalling and made sure my firewall is not blocking Corel.  Any other ideas what could be causing this?  My internet is working perfectly, it just seems like Corel can't connect to it for some reason.  Thanks!
