You're all crying because Nexon isn't perfect. "Oh Nexon always fails".
I'd like to see you code a better hack shield than Black Cipher, I'd like to see you code a better website than them.
Oh the PHP coder made a booboo, are you going to cry?
Either way, it happens to random people and it's due to their coding. They're trying to fix it, just wait it out and it should go away, that's how it worked my friend.
