alpha360 Magazine comes with various WEB Service projects and example projects.
After compiling and installing the included WEB Services, it is always a good idea to "refresh" them in the example projects also.
Just delete them from the example projects and re-import them, using YOUR WEB Service address.
Sometimes, especially when using the local WEBDEV application server, you may need to delete them first on the WEBDEV application server AND from your local IIs server, before installing them.
