It didn't work. I pressed Fn+Esc then uninstall the program and pressed Fn+Esc again. Then, I unpluged the keyboard and reinstall the program and try to customize the color. When I restart my computer in next day. The keyboard become default setting
Few weeks ago, my keyboard start reseting the lighting option to default everytime I restart my computer.
But in the program every thing was fine.
