Yesterday I was playing, all good. This morning the first track loads normally, then no track loads correctly (error : "analysis is required for quantized feature") : no waveform, no info. For all tracks.

I have had this problem a couple of time before, but then reooting the xdj fixed it. This time, no matter how many times I reboot / unplug the USB / unplug the xdj, the problem stays.

My firmware is up to date (2.21).
