Problem consuming an External Web Service

Hi all, I'm having a problem while trying to consume an external web service, this service return some file as attachments, the web service works just fine when I try to consume it in SOAP UI, or visual studio, but the problem comes when I try to consume it from ByD Studio, I think this is because in visual studio I'm using something like this:

          BasicHttpBinding binding2 = new BasicHttpBinding();

          binding2.MessageEncoding = WSMessageEncoding.Mtom

this is used to handle the files, since the web service use MTOM to do it, but I don't know how can I do this from ByD.

the only think I get when I try to consume the WS is an message in the "CommunicationFault", that says that "An exception occurred".

I really hope you can help me.

Thanks a lot in advance.
