pioneer ddj rx - bugs while playing

I updated the newest version of rekordbox and of my controller (pioneer ddj rx) yesterday to the latest versions.

Since them, i have problems while playing songs. When i playing 10 or 15 minutes the loops does not work longer. I can't create loops with the loop buttons (all of them testet) and other loop combined functions does not work longer too which uses in performance pads. When i start a loop, 1 the loop is always 32 beats big no matter what size i change or 2. the loop only reacts not. Sync functions also works not every time. It's always one deck where error has. If i load a new song, the error is sometimes no longer there. I don't use sync as much, but its important for fast transtions or other smaller things.

I can't dj when loops not working.
