>yes, I know that. A couple of months ago I saw that when I first tried to access UT's WS from .Net. Haven't you found any property that you may need to set in that add-in that Martín had mentioned?

The installation works fine. I also register again the WS just in case it needed to be reset. I don't know much more than that. It still bugs me that this isn't supported natively as this was released a year ago.
