Reply to Traktor Problem :/

So I downloaded the latest update for traktor. now it kinda fuxed me. every now and then the audio stops working and I have to reconnect the USB so the sound comes back :/ Im using windows 7 btw. If anyone has any suggestions that'd be awesome. Maybe my latency settings are weird? If anyone has a PC laptop and Traktor with the S4 and it works perfectly 100% can you post your latency settings? im stuck here...
