Hi guys, My right deck on traktor Pro 3 (scratch) is showing right deck missing. It still plays but won't let me calibrate. I've swapped cartridges around and the left deck plays fine, so it's not that. Checked all cables etc. Just can't get to the bottom of it. I'm using an old Windows 7 laptop but never had any problems before. Help please. TIA
P.S.
Native access is no longer available for Windows 7.
