I have recently purchased a Denver VPL -120 portable turntable. My computer recognises I have connected it, but recognises it as a disc drive and tells me to plug in a disc. I have tried it with a computer running windows 10 and also with a computer running windows XP, both computers tell me the same thing. Any clues, please, as to how I can resolve the problem. I wish to transfer my music on vinyl into the computer as mp3
