First, that web site has problems for new registrations (our deal with a web site developer went bad, so it has not been updated/fixed). But there is a utility I can use to manually confirm your registration, so I did a search of pending users, found gnatd and manually accepted you, so if you can remember your user/pass that you used, it should work now.
Second, the $language is a new feature I added to help more easily adopt other translations. If you are having the trouble you describe, I suspect you don't have the most current Maelstrom version that supports this new $language item, but rather you have an older version, before I added the feature. Update to the newest Maelstrom version and this problem should disappear.
