I tried to use MSSOAP.SoapClient30 but got the same result. Here is the code:

LOCAL soapClient as MSSOAP.SoapClient30
LOCAL oResult as Object, x as Object 
oResult = null

soapClient = CREATEOBJECT("MSSOAP.SoapClient30")
soapClient.MSSoapInit("https://../License.jws?WSDL", "License", "LicenseSoap")

x = soapClient.Authenticate(0,"PASSWORD",oResult)

The error was "Catastrophic failure" again.
