Razer Kraken X 7.1 surround sound download

Hello! I have the lovely Razer Kraken X headphones and had major issues in downloading the 7.1 surround sound download software, claiming as it has been downloaded. I had major issues in getting the headphones to work and must have cancelled it somehow. Is there a way I can get the 7.1 resent to me? With very best wishes, Jay London, UK
