Error creating project from WSDL + XSDs

This worked before but now does not.

Using 'New soapUI Project' and specifying Initial WSDL as:

https://wsnet.sendwordnow.com/webservices/v2/users.wsdl

The WSDL references 3 XSDs:

https://wsnet.sendwordnow.com/webservic ... -USERS.xsd
https://wsnet.sendwordnow.com/webservic ... -USERS.xsd
https://wsnet.sendwordnow.com/webservic ... -USERS.xsd

The process starts fine but 'hangs' on one of the XSDs - it seems that, rather than reaching across the notwork, it is looking to localhost for one of the XSDs.  These excerpts from the soapUI log:

.

Why the switch to localhost:3101? 

This started happening with version 2.5.1 (where it used to work), also happens with 3.0.1 (new install to see if it resolved issue).
