I've owned my DMXIS for several years now and love it, but I've never encountered this problem before and hoping someone can assist quickly.
I use my DMXIS program on my Macbook Air with your program and transmitter box part number 70570. I loaded my program, connected my box to the first light fixture/moving head and it was working fine, within a few minutes the first light fixture started moving in all directions and changing gobos and colors all on it's own, I selected several programs I've programmed and it was non-responsive.
I then disconnected the DMX cable from the light fixture and it stopped.. Plugged it back in and it started going crazy again!
I performed a hard shutdown on my laptop and DMXIS program, loaded everything back up and now it's not responding at all..

Please help, I'm not sure what's going on and have shows coming up this week!
Any help would be greatly appreciated.
