90006 Error on ONE Character

My main character on Cactuar cannot be logged into. I crash the moment I see the loading screen go away, or I get on for 1 second and nothing is responsive and then I get an error and get kicked off. Always 90006 error. I can log into any other alt on the same account and it works just fine, even my alt on Cactuar "Tattered Wings", but there is something wrong with my main character. The support lines are closed until Monday so hopefully something can be done by posting here.

PS: This is not a network issue. All other characters work, and my girlfriends characters also work on the same network on her PC, plus the router and modem has been restarted.

Can login and play as normal today. Issue must have resolved itself.
