I had the problem, too - even with the most current KORG USB MIDI driver. It got to a point where I had to go back to a Windows recovery point to get any MIDI devices working again. I only wanted to get my nanoKONTROL2 installed and this couldn't be so crazy complicated, I thought. KORG extended their uninstall utility to show more than 10 MIDI devices but Cakewalk doesn't find the nanoKONTROL2 on device #14. I'm not daring to install the KORG driver again and I will follow Mark's
