Panic. The tempomixer on controller is still not working and it seems nobody can help me.

The tempo is not working anymore on my XDJ-RX. The software asked me to update the software and so I did. After that suddenly I can not change the tempo anymore on my controller. PLEASE HELP!!!! I need to play tomorrow night. This is a disaster. :(

 

I am using record box. A few suggestions I tried already. Move the tempo all the way up and then down and then to the middle. It still doesn't work.

 

What can I do? I have a dj gig this weekend. PANIC
