>.> either you renamed theduel.exe to gunz.exe (or vise versa) or you have too old of a runnable

I think i figured out the problem, I'm using xiao runnable and it has an encryption that only a certain launcher can read. so when i tried to run gunz with another launching program it failed to open and gave me a serial error.
