I left Cough for Dinner, and when I came back to log in, that error appeared. The game was normal two hours ago. 
How to fix this , admins !?

i open a ticket, asked to uninstall the game completely. I did the process. But the same error appears.
It did not work, I uninstalled the Tree of Savior completely, including deleting the folder inside Steam and clearing all system logs. I downloaded the game again, and the error persists.
I am premium and lost 2 days already. =(
