Cannot get wsdl using authenticated proxy

Hi.

In my company, we use an authenticated proxy for accesing internet.

I'm trying to configure SoapUI to do that, but it seems to not to be working fine.
There is an error on http log:
Fri Dec 14 16:25:21 CET 2012:DEBUG:<< "HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )[\r][\n]"


Of course, I fill the gaps in the proxy configuraton.

If I try to see the wsdl using a browser, it works!


Could you help me?
I'm on soapUI 4.5.1.1-SNAPSHOT ( I read that the roblem was solved here, but, could be another problem)


Thanks!!!
