One day i was playing playing it normally and then other day I can't login... This is what the yellow letters wrote Cannot login. Also a pop-up window opened and it said some stuff. The next day it was the same but in a few hours it automatically fixed... What just happened? I was all like WTF?
(The last part was not necessary... I know)
P.S.
I have a normal connection.
Anti-virus works properly and does not block CS2D.
