Hi. I just recently bought a Corsair K70 RGB and it only partially works. When I plug in the keyboard, it lights up and most buttons works (keys, volume, ect). BUT I cannot get to be able to change colors! I also have the Corsair Sabre RGB. The mouse is recognized by Corsair's program: "Corsair Utility Engine", but not the keyboard. In Devices and Printers, both are shown. What am I missing? What should I do?
