Error Adding WSDL to Project with Basic Auth

Hi
soapUI Version 4.5.1

I'm new to soapUI and I am getting the following error when I try to add a WSDL created in Eclipse to soapUI. The same WSDL I can access using IE or Chrome.

soapUI Log

ERROR:An error occured [com.eviware.soapui.impl.support.definition.support.InvalidDefinitionException], see error log for details
