Psychochook

Hi, I recently purchased the Challenger Prime V2 keyboard. I went to the Product Page for the keyboard - https://www.ttesports.com/Keyboard/336/Challenger_Prime_V2_/productPage.htm?a=a&g=ftr#.XkjQqmgzaUk and clicked on the Software Download link at the bottom of the page only to get a 404 error. I sent a support request to the company but got no response. Does anyone know where I can download the software for this keyboard? Thanks
