Is your game crashing after the patch ? If so, enter :)
So, i'm aware that many individuals like me have experienced some issues after the Nexon maintenance and patch, a few days ago. One of the most common issues was the game crashing immediately after the loading screen, or at random intervals during gameplay. I came by a solution today while browsing around and asking people, and has worked for me since.
It's simple. If you start using the combat arms webpage, start the game and close all the browsers before the game starts loading. I'm not sure how this makes any difference to the mechanics - apart from maybe reducing some lag, but it definitely solved my crashing issue.
