Problem with not verified SSL and Basic authentication

Hello, I am a user of SOAP UI since a long time,

The problem is that I was using the version plugin (sorry but I don't remember the version) and since few weeks, I updated the plugin and now it is not working my WSDL. This is the Log:

Wed Apr 09 11:47:37 CEST 2014:ERROR:Failed to load url [https://isae.aucorsa.es/Public/Aucorsa.svc?WSDL]
Wed Apr 09 11:47:37 CEST 2014:ERROR:An error occured [com.eviware.soapui.impl.support.definition.support.InvalidDefinitionException], see error log for details

And the Error Log:

After these few months of trying and trying with the Desktop version of SOAP UI (4.5 and even with the newer 5.0 BETA) with different errors but no sucess (SSLHandshakeException, InvalidDefinitionException and so on...), one day I was trying from another laptop which had an old SOAP UI 3.5 version and it worked!!!

I don't know what's the problem, I guess it is related with the certificates (The WSDL I am trying to connect with, has not verified certificates..) but I cannot connect anymore if I am using the newer versions.....
Is it a known bug? Or is it something with the gonna be corrected?

Anyway, thank you very much for the job and for the community!
