Razer Blackwidow X Chroma key problem

Issue:

Hi all,

I have been using my Razer Blackwidow keyboard for a long time now, but I have suddenly come along to a problem. Whenever I attempt to press the keys, the underkey lights stop working and the key that I press fades green in and out. After around 10 seconds the lights come back on.

MAIN POINT: Chroma does not update keyboard lighting. When I change colours, my Razer Lancehead Works and changes, but the keyboard does not.

Thanks
