Every time I try to login, it gives me the message "You have been disconnected from the server." I've forwarded the port 47624 UDP/TCP on both my PC's firewall, router, and modem. I've allowed java.exe and javaw.exe in my PC firewall. I've restarted my PC, router, and modem. I've updated Java and my graphics card drivers are up-to-date. I've reinstalled Spiral Knights twice. My PC can handle Crysis on High; its not my hardware.
Unless the port 47624 is wrong, then there is something wrong with your servers or game client.
