I’m frustrated

USB Light is blinking when plugging in NS7II Midi into MacBook Pro El Capitan OS X

I have recently purchase a new Macbook Pro and had to re-install DJ Serrato 1.9.2 and update Firmware V.1.05.

I followed the instructions and actually had NS7II work for a second.
After a reboot of my Macbook Pro. It doesn't recognize NS7ii and USB light on the Mixer just blinks.

I uninstalled Firmware and re-installed it and same issue.

Please advise.
