For future reference if the .wsdl is either malformed xml or schema invalid the .wsdl wont load (which is the reason why your .wsdl was failing to load).
If you ever have this issue again, just launch your .wsdl in something like xmlspy (or a browser)....anything with am .xml parser would do to check the file.
if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
