This happens if you use the .NET library, where you forget to include App.Config. The library has a bug: the URL of the Adwords service is hardcoded to http://localhost. The URL can be overridden with the entry in App.Config. Note that calculateing the authentication token has no problems: that is done using a different service, whose URL is hardcoded correctly.
You can solve this problem by either adding an App.config or changing the sources of the lib. -- You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
