"The server you have selected is down, therefore you cannot access it(8)"

Hello everyone. I downloaded the Aion lightning 4.0 1-click by Dwarfpicker and followed the tutorial, however it's not working. When I enter the game and get passed the log in menu, the server status is "down" and when I click on it I get the error message "The server you have selected is down, therefore you cannot access it(8)". So I assume that means by gameserver is not starting properly, but I dont know why. I've been searching for hours but can't seem to find anything on it, the ones who do ask questions about it never seem to get answered. The error message in my gameserver is:

===============================[ GameServerLog ]===============================
