Was playing Minecraft this morning and everything was fine. Then just now it won't work. Can play Singleplayer okay but not Multiplayer. All I get is a "Connection Lost" followed by "Failed to login:". Please see below. Have checked my password and user name. This happen with PVP SMP and other servers. I have tried re-downloading, re-setting my internet, re-starting my computer and all to no avail. Java here is SE 6.

Mod Edit: Picture Removed. SessionID was shown.
