As i just noticed, the login database is OFFLINE due to some problems with the hoster. Those who can still login have their session cached in the gameserver. If you want to stay able to login, you have to do so at least once a day.
We can tell you how long this situation last, when we were able to contact the hoster.
Edit: The damage has proved to be permanent. I talked about some solutions ingame. Ask your guildmates if you were not able to login. Please Tell me what you think about it via private message.
