At the point when I run the wcftestclient utility I get the following error:


"Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service."


I did everything EXACTLY the same up to this point? What could be happening???
