SoapUI - failed to instantiate properly

Hi,

I've got two different applications that has webservices and they behave differently.

Both webservice were generated and built with the same settings but when I got test them one gives me the reponse with no problems, the other gives me the following error:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
