Character still in game!

My character is still ingame however I am NOT! I got the error code 90000 at 11:00AM this morning and my character is still in there and I am unable to log in to the server, I can however log in to other characters (not same server) and play those characters but I do not want this I want to play on my main character.

Please help me I would appreciate a response from a GM or someone from SE....

Server : Adamantoise
Character name : Star Thegreat

don't hope for 2 much i been stuck inside a dungeon for 2 days now

You may be stuck for a long time. Many are experiencing the same error codes. Best to load up an old game and come back to FFXIV in a week or so; whenever they update their server capacity.
