I'm also getting the 90000 error and it's making the game unplayable for me as well. I am able to log in, and the different chats work, however other characters around me do not move around like time is frozen. I'm on Behemoth and just started getting this issue about 6-7 days ago. Not sure what to do besides just wait on it to fix itself since I had played the game for a while before this issue started.
