Corsair K55 suddenly stopped working

[Zip]

Hi

All of a sudden my keyboard has stopped working.

I changed my monitor today. It was working fine before that but hasn't worked since. iCue has also stopped detecting it, but the lights are still working on it.

I've reinstalled iCue to no avail and also tried resetting the keyboard by holding down the F1 & Windows key. I've also tried different ports.

Any advice would be greatly appreciated.
