Mick, It sounds like you have determined that the ErrorCode field value is BadAuthentication. According to the ClientLogin documentation<https://developers.google.com/accounts/docs/AuthForInstalledApps#Errors>, BadAuthentication indicates that the username and password is not recognized. Please verify the username/password.
On the other note, ClientLogin usage is deprecated and will sunset in June 2014<http://googleadsdeveloper.blogspot.com/2013/09/announcing-sunset-of-clientlogin-in.html>. Please use OAuth 2.0 with the AdWords API<https://developers.google.com/adwords/api/docs/guides/authentication>instead.
