I know the error you are talking about. It's a timing thing, like if you idle too long on a page you got "disconnected" (except you are not...) or someone is using your account from somewhere else or some BS like that.

Take your time Shikifan, there's no rush^^ also, for visibility, do it in a newer comment box please.
