Hi all, my name is Cristian. I have TRAKTOR 3.31, a vestax VCI 100 and a laptop with 2gbram, dual2core @2ghz. Well, I always used a usb soundcard as a monitor. All was OK, but 2 weeks ago I bought a firewire soundcard, a Presonus Firebox, and since that, I've been troubles: While a track is playing, suddelnly the music stops... it just stops, and I don't press any key. So I have to exit from Traktor 3 and run it again, but after a while, same thing happens. Please somebody help me with this. Thank you guys.
