We are experiencing problems with our update system at the moment. We are trying to sort it out. In the meantime, you can download a new installer, which includes the updates, at
http://tribaltrouble.com/download.php
It might be wise to backup the files 'savegames', 'registration' and 'settings' in the Tribal Trouble directory.
PS: I can't imagine that we would ever drop support for our multiplayer server without opening up the source for the server. But of course, I should never say never
