XDJ-RX disconnect with rekordBox performance.

Hi.

when I play xdj-rx rekordbox performance mode midi, disconnect xdj-rx but the music plays on, xdj-rx does not respond. Only restart it and rekordbox helps. Sometimes it disconnects after 20 minutes sometimes 40, differently. I reinstall drivers and rekordbox, still too same.

Xdj-rx firmware ver. 2.1

rekordbox (performance mode) ver. 4.2.4

Please help.
