Problem with Razer keyboard

Hi I have problem with new Razer Cynosa Lite. At first plug in keyboard worked and razer synapse started with installing, after all finished, when I got sure everything works, I unplugged keyboard and turned off pc. Later that day I turned on pc and plugged keyboard again, but this time no reaction at all, keyboard just doesn't work. Tried installing/uninstalling drivers, plugging to other ports but keyboard just doesn't show any signs of life. I also tried to plug it to another 3 PCs shagle, but it still doesn't work. Is it possible to fix this somehow, or is it already dead azar? Thanks
