Can't Load the audio driver for ddj rb for rekordbox

Hello guys, 

I bought the DDJ RB yesterday and installed the rekordbox dj, activated, downloaded the latest driver as requested and I can use the controller as a midi but i cant load DDJ audio driver. 

I have a MacBook Pro running on High Sierra. Can you please let me know how can I fix this problem as I feel very disappointed. 

Btw I'm a music producer and I'm a heavy user on abelton and couldn't imagine it will be this hard to install this controller.
