RB 5.4 issues with DDJ-1000

Hello.

Yesterday I had two big issues with new RB 5.4 update & DDJ 1000

1) After hour of use at gig there showed interupts (disconnection between software and controller for 5-10 seconds).

Basically it acted like I was restarting DDJ1000 with power button, and issue showed more than 10 times during 2 hours of use.

2) Second bug showed only one time after first controller restarted (I get same error few months ago  with earler RB versions too). When controller disconnects and connects back again - CUE PLAY function on headphone don't work properly. Master sounds on headphones even CUE PLAY is not pressed on any mixer channel. I noticed that if I press CUE button near BOOT OUT fader - headphones started to work properly. After next controller restart issue with cue dissapeared.

Perhaps You could test conntroler functions if it suddenly restarts..

I couldn't find elswhere previous RB 5.3 version, can I get link?
