First error in Korean is that you are probably logged out when the patch is complete. Try to log in again via the website.
Second one,I think, is your Direct3D/DiirectX is up to date?
Ah, thank you, that helped =3
I been getting this again after the patch, did u just relog?
This often happens when you try to open the game, but your login session already expired, so just relogging should help.
I am having this stupid error again even if I relog oh god.. annoying ****, and I can just play normally yesterday srsly...
relogged for the nth* ****ing time ._. srsly... this is making me rage what a shitty troll.
