Whenever I try to log into the game as one of my characters, as it's loading (can hear the Ul'dah bgm) it suddenly stops, and brings up this message.

"An error has occurred. (40000)3".

I chatted with someone from Square Enix, who recommended I double check my network settings. Everything seems to be in order, and I can log into my Miqo'te in Gridania just fine, but can't log into my Hyur. I'm afraid there might be something wrong with my character.
