Problem the linking CDJ with Djay pro 1.1.1

After pressing the Link button, Djay doesn’t allow me to select decks 1 and 2 on both CDJ screen, no playlist comes up and it does not ask for Pioneer CJD/XJD audio setup either.

This means that I cannot play tracks nor gain audio.

please help.

Which CDJs do you use? Only the 2000 Nexus and 900 Nexus are supported, yet.

I used the CDJ2000 Nexus.

It located my laptop and I got the display messages, but it failed to map the decks and also failed to configure audio.
