I came home from work and the show computer had crashed. That in itself was odd, but once I restarted it, I didn’t have access to one of the com ports that runs the show. After a little checking, I found that my usb hub had died. Good grief. I had one open usb port on the back of the pc, so I plugged in there, restarted and held my breath. Bingo. Show was up and running, only about 25 minutes late. Sorry to the folks who had pulled up in the van 🙁 Hopefully you have another chance to come by.
