XDJ RX - No new firmware and missing from site?

I've had issues with the XDJ-RX ever since updating it about 4/5 months ago. I can't use Rekord Box "Performance' mode as the pitch faders dont work. I've got a unit still in warranty that I can barely use!

I'm now scared to update my Mac as I don't want to lose 'Export' Mode.

What can i do?

Thanks!
