GameBooster Detected As Hacking Tool

I am playing Cabal Online and the game uses GameGuard as game protection. I have GameBooster 3.5 beta and whenever I turn on or activate FPS, a window will popup saying game hacking tool is detected. I can’t use video recording, FPS benchmarking, and screenshot. I already followed the instruction on the message. I rebooted the computer and started the game again.

But still, whenever I turn on FPS, the message appears again. The message doesn’t appear when FPS is turned off.
