Emergancy Loop when linking with rekordboxon Xdj-RX

As I have re-analysed my playlist and connected my pc with link connection wired with xdj-rx :

1. It is taking time load on both the decks.

2. After a minute and half it goes automatic on emergency loop on the any track  from the playlist that I play and on controller its show "Some player function limited". 

But USB stick are working properly on the controller
