WDF IS WRONG WITH YOU?
Don't complain, there's been a bunch of patches lately, meaning game instability; read the sticky.
If you have an actual issue, go post it in CA help.
EDIT: Also, if you're unhappy with the level of service Nexon is giving you, EVEN THOUGH IT'S A FREE GAME, then just leave.
You should be happy that they EVEN support CA.
They could be like TF2 & Valve on the XBOX...
