Unable to load WSDL

Hi
I am unable to load below URL wsdl, I get below error, however the website support claims they are able to load the same link in version 3.0.1. I tried 3.0.1 but its not working and I am currently using latest 3.6.1 version of Soap UI. Please advise.

WSDL URL:
http://webservices.sabre.com/wsdl/sabreXML1.0.00/usg/SessionCreateRQ.wsdl

Error Log:
