Can't play on any Server

[auh06]

Whenever I click on a server the screen is black and the cursor doesn't move at all. The music is still running but it just freezes. Any ideas?

Here is the Error:

Buffer Overrun detected!

Program: C:\Nexon\Combat Arms\Engine.exe

A buffer overrun has been detected which has corrupted the program's internal state. The program cannot safely continue execution and must now be terminated.
