Error while creating webservice Connector

Hi all,
I am trying to create the webservice connector using the following wsdl

http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdl

But am iam getting an error like
[ITD.0012.0012] Error occurred while creating Web Service Connector

But when I saved that wsdl to my local machine and tried to run that webservice connector I got the following

Thanks
Datta

The WSDL at this URL generated a web service connector Flow service with no errors on IS 6.5 SP2. The getRate operation keeps returning null pointer errors, probably because I don’t know the country codes to enter or because it is out of service.
