Sounds to me like a connection problem. The game has been down a number of times since January first. Based on the time you posted this thread, it seems you're trying to log in when a HUGE number of people are also trying to access the game. However, this could also be based on your own connection, has it changed any? Try getting closer to the modem.
However, you may also want to try deleting the Feral Heart folder from your C-Drive and reinstalling the latest setup. This seems to fix most bugs with the game.
