Hi, I have a problem but I'm not sure what the problem is or how to fix it. I was DJing on the weekend for 6 hours and I encountered a problem I haven't had happen before. I have a traktor kontrol s4 mk 3 that goes through trator pro 3 that is on my hp laptop which is an I core 7 with 16gb ram. About 2/3 of the way through the set, the music just shut off and the software became unresponsive. I closed the program and restarted it and continued playing and the problem didn't happen again but that fact it happened at all bugs me. Given that after I shut off the program and restarted it, everything worked fine again, my thoughts are that maybe the program froze because there were too many process going on but I'm not sure as I'm not computer savvy. I've taken the laptop to a computer service shop and they servicing the machine to improve performance but what if that doesn't work or what if that wasn't the problem in the first place? Has anyone encountered this problem before and how was it fixed? I'm sorry the message is vague but I can't think of how to explain it in any more detail. If anyone can offer me advice, that would be much appreciated. Mark
