Not sure what problem you are referring to. The 2nd photo shows that the player is running in emergency track mode. The USB Media or SD card lost connection or got ejected. Your 3rd photo indicates that the CDJ is not connected to the internet. The Player doesn't need to have access to the internet to operate. Therefore the last picture is not a problem indication - just shows the status.
Without more information what you did or what is not working, it is hard to help you.
