Everything should be back running normal now. However, due to the server upgrade, we also have a new game IP now.
Those who use the batch file to connect, update it:
start darkeden.exe NEWSTART Futec(220.127.116.11:9909)
If you don't know how to create a batch file or experience any problems with it, download it from here: http://darkedeneurope.com/files/start_game.rar and extract it to your game folder.
PS. Let your friends know about this news, they need to update their batch or they cannot connect.
