I recently just got a Sades SA-708 7.1 headset, and I am trying to install the 7.1 software so I can use surround sound. I don't have a way to play the disc that came with it, so I went to the Sades website to try and download it. I tried the Windows 8 one (because that's the version I have), but when I do the setup.exe, it says to plug in my headset. I've tried all my USB ports and none of them work. Anyone know the solution?
