*that's because you're using Coolite version 0.7.0, and localization support will be awailable only in 0.8.0 and higher.
As i understand, 0.8.1 is accessible only to members who have bought support subscriptions.
But yes, the fact that examples.ext.net demostrates version 0.8.0 which is not currently accessible as release version is a bit confusing. I am wondering myself when this new version will go out.
