Hi, I just got a Sony MZ-N505 MD player and I cant get any drivers to install for it. It isnt recognized by SonicStage. I do see it as a "NetMD Walkman" ins Devices and Printers. I'm currently running windows 8.1 and SonicStage 4.3. I have manually downloaded drivers from this site, but when I go to install them I always get some random hash error. Any help would be appreciated.
