I'm getting the error code 43 for my DM6

Well after 2 years using my dm6 with my old computer (windows 7) I get a new computer with windows 8,.1, and now it doesn't work? I'm getting the code 43 for usb error. I read on here somewhere that Alesis's response was "well we know the dm6 is working ok". But is it compatible with windows 8.1? All I know is it's not working, and I have 12 other usb devices that do work?
