Tried to use emulation program last weekend for a gig. Had everything working great in my garage ahead of time. During the show, the lights would simply blackout. If I unplugged the USB cable from the computer and then put it back in, everything would work again for a few minutes, then repeat itself. The lights themselves would have flashing addresses when not working, so not getting a DMX signal. My computer is MacBook Pro 2.53 GHz Intel Core 2 Duo, OS 10.8.4, emulation v 1.3.40.
