@waynecox ... I had a friend who is a specialists at programming computers working on this thing. What we ended up doing is going USB on it. Once we did that, everything worked as far as backing up and updating. That com to com thing has given us more problems than what it's worth. There is an adaptor that will go from usb to com that you can purchase from a retailer. One thing that I did notice was that when we brought the backup back to the SD1, 99.99% of it was correct. There was one scene that we found to be corrupt for some reason. So, all I did was redo the scene on a different scene channel and then update the show (song) step to that different scene. For some reason, I still can't record over that corrupt scene. So, we'll just leave that over there in it's own little world and hope it doesn't come over to my world, right? Hope that helps.
