It started, when I noticed, that Guild section in Social menu stopped to update. I wanted to invite some of my guildmates to my party(it was arena) and wrote it to the guild chat, but it didn't send. I said to my friend, who was in party, to wait me here, and I relogged. After this, trying to join his party, I got a message about an error. Now I can't access to Guild Hall, Haven and parties, can't even send a mail, but can use /tell and write to guild chat. My guildmates adviced me to contact with OOO support, but www.spiralknights.com/support#mail doesn't open.
