Honestly, the fastest way to answer any question or fix any issue in this game is to post about it on the forum. Seems like 9/10, folks figure out the issue or find what they're looking for immediately after posting. It's just part of the forum's charm.
As for your issue here, I've seen the signature say invalid user when the game server has been acting wonky. It usually passes quickly though. Never been something to be concerned about.
