Greetings,
European Aion server is now being managed by Gameforge.
As of December 12, 2012, all European Aion game accounts that were not yet migrated to the Gameforge European Service, were removed from the NCSOFT Service. You will need to contact the Gameforge Support team for assistance with a European Aion account. You can reach them by visiting https://aion.support.gameforge.com/
