sounds like they saved over your show file, or the console is loading the show file they used. Should be easy enough to re-load a previous backup (assuming one exists)
lightingtrainer.com has some good resources;

Alternatively I know a guy who hasn't been up your way in a while but has some free time in December 
Thanks for the link James. I would train for the board if I thought I had an eye for lighting. And the patience. I've found the solution is to just hire someone. Lot easier just to make a call and fill out a PO.
