Error 90000 Reborn.

Same thing, can't send tells, talk in LS or join any instance, if I try to join a quest i get disconnected from server (error 90000). Got a red box with a "play" button infront of my name constantly.
Server: Shiva (EU)
Character name: Sozu Rogberry

Same thing here

same issue :( Was loading instance when maintenance happened.

Same problem, was loading instance when maintenance started.

Server: Gilgamesh
Character: Dingo Fallstar

I have the same problem as well.

I was loading instance when maintenance started, got the error and now I can't communicate with everyone as I am "bound by duty". Can't load the quest instance either nor can I abandon it.

Character Name: Similia Alka
Server: Hyperion

Same problem.

Server: Gilgamesh
Character: Strahdd Delacour

Error 90000

Was Loading Duty, Honor, Country when this happened. Now I'm locked out of my Linkshell and Friend's List and stuck in Another World status

World: Sargatanas
Character: Faceless Fresh

Hopefully it gets fixed permanently soon. I was affected with the disease during open beta and was forced to spend any leveling time grinding for it rather than questing. I can't open up any other classes than the few that I have because this error just won't let me finish the story quests, but others here know what that's like. Godspeed Square-Enix. Looking forward to finally being able to play it as intended.

Greetings,

Thanks for the report on this. We're currently investigating this issue and once I have more information I'll be sure to post an update.
In the meantime, if you're affected, please list your Character Name, World and what you were doing when you encountered the issue.

joined the 90k train too on Excalibur server.

I was entering the instance for " the rematch " class quest
