DDJ-SZ and Pad-Problem

Last night I had a Little Problem with my DDJ-SZ, and here with the pads of the right deck: Afters hours playing I could see that the pads are not lighting and do not react, when I push them afters I loaded a new track in the deck. I mean the cue Points. Every other function is working, and when I started Serato DJ again, the Problem was gone and everything works again how it should. The Problem is by every new track that I load in the right deck.

I use a Macbook Pro 1.8.5, Serato 1.6.3 and newest Firmware 1.18

Thanx
