Game crashes for no reason!!

1. Change the compatibility settings for CombatArms_Direct.exe back to None if you are using CombatArms_Direct.exe to launch the game.
2. If you're a programmer, check you don't have any frozen threads in any processes. If HackShield (or Combat Arms) detects a frozen thread before it starts, it shuts itself down.

maybe theyll fix this after the maitenence

Haven't you noticed there's always a server patch for a server patch? And the messenger and the clan chat don't work? Do you honestly believe Nexon could fix anything when they can't even fix these two problems? With each update they add more hacking programs HackShield scans for, so if anything, updates increase lag.

no i noticed that after every patch it gets worse every time

My point exactly.

I won't give you the same answers like upgrade your drivers, etc. because I'm assuming you're knowledgeable like I am. Your best bet is to submit a support ticket to Nexon and let them know you've tried everything. It may be OS specific or system specific and if enough people complain about the same issue they'll investigate it.
