Getting message "no endpoint set for request" when trying to select a URL to test

I am using soapUI NG PRO.  Everything has been going well until today.  My SOAP requests in my project and testcases have lost all of their endpoint URLs so they cannot be run.  When I select the down arror (which appears grayed out)  I am getting the message " - no endpoint set for request -".   Even adding a new SOAP request does not resolve the issue.  Selecting the Projects tab I have one project with six endpoints.  They are all havng this problem - existing and new requests don't have an endpoint so nothing can be run.  I've tried closing and reopening Ready API!. The problem still persists.  

Attached is a screenshot.

Looking at in the SmartBear community I found this problem reported but no fix was listed.

Any ideas?

Thank you,
