I have this problem too. My pedal is only 4 months old. Was using it on my sister's window 7 (middle pedal working fine) but when my sister's laptop broke down, I used my own laptop, which is quite old but with Win 10 installed. It keeps disconnecting-connecting when I press the middle button. I read in the forums that assigning the play button either at the leftmost or rightmost button will do the trick and it just did. Still no idea why the middle button on win 10 has problem though. I'm sure my pedal is not dirty because I have put it in a zip-loc kind of bag so it does not accumulate dirt.
