Hi there. I have just gotten myself a K65 Rapidfire. (I was using Strafe RGB previously) Downloaded the latest CUE and started running it. However, the volume keys, mute key and windows lock button aren't working. I don't have this issue with the FN Media keys, and previously it works well with my strafe. I have no Google Play Music or Winamp. I don't think it's a hardware issue. I have also restarted and switch HID services on, and set it to automatic startup at the same time. Restarted my computer, reinstalled CUE a few times. Still doesn't work. Anyone has any idea how I can get the keys to work? Thank you!
