BIG ISSUE! My decks on Rekordbox remain grey (not orange then green) after loading a track

Hey guys, Pulse,

When I plug my mac (RJ45) on my XDJ RX with rekordbox I got an issue!

My RX recognize well my MAC because when I click on REKORDBOX button I can see my mac.

Then on the software I can see the LINK button and I can click on it. There are 2 decks but they remain grey! Normally it has to be orange and green when you load them!

The deck load the track (my decks are lighting)  but it s still grey and I can not play the track. It should be orange when you load it and green when it s ready to play...

I got the last firmware, last rekordbox, wifi shut down, firewall shut down, tried many RJ45 etc...

Could you please help me out?

Many Thanks
