Connecting to a webservice

Hi,

I am having problems connecting to a webservice provided by a third party. What i did so far:

0. Setup my project and added System.web and System.Web.Services
1. Downloaded the WSDL file provided by the third party.
2. Used the wsdl program provided by Unity to generate a c# file from the original WSDL file.
3. Added the new C# in Unity.
4. Wrote a TestConnection.cs class (see below).
5. I double checked my login/password/domain but i keep getting the error:...
