As Miyoko said that message is usually caused when the character disconnects suddenly and has not been logged out yet. Usually giving it a few minutes will allow the system to kick the character offline so you can access it once more.
If it takes longer than a few minutes you'll want to submit an in-game petition from an alternate character as Miyoko suggested.
It looks like you are in-game on that character now so I'll assume the issue was resolved. :)
Good luck to you, Lanthanide.
