If you are having problems with your licence key/s, please double-check them first, and try entering them again. If you have any Add-Ons, or extra vessels, please make certain that you're entering the correct key when requested. If this still doesn't work, you can send your licence key/s to an Administrator (preferably Mad_Fred) by Personal Message (http://80.95.161.114/shipsim/forum/index.php?action=pm;sa=send;u=14799) (PM). The key/s will be checked for you.
Please don't post your licence key/s on the main forum, thank you.
