I beg to differ. Pioneer has done an amazing job creating this new version and through our beta tests, nobody ever complained about the software or its exports causing the players to become unresponsive. I'm thinking it has more to do with your device and the library therein. Can you give me a bit of info on the device? Did you previously use the same device with rekordbox 2.x? Did you format it prior to upgrading to 3.0?
