Nexon's Black Cipher

So I'm developing a hack, and I run it with combat arms as I code the base to make sure everything works before I move on to something else. So I run the hack, and Black Cipher (Nexon's not to be confused with Noobs Hack) stays open very long in the bottom right corner and then the hack just crashes. I run it again, and the same thing happens. Then I run it once more without changing anything, and then it runs. It makes me feel like Black Cipher was going through my computer lol..

Even so would that explain why it just ended combat arms..
