I have already tried it and it was working perfectly (I could set some macros and save my profiles) but now when i press the "M1", "M2" or "M3" key, most of the keys doesn't work. The only way that the keyboard works is when i unplug and plug (it does but the macros doesn't work). I bought this keyboard only for the macros if I'd known that this would happen I probably would have bought another simple keyboard . I've attached a photo (this blue lights keep flashing endlessly) and a video that explains my problem.
