Got a weird problem today. I have an LC1100 with chemstation that was working fine until today. When I launched it, the chemstation loaded up but it the system diagram didn't load. If you go to view->system diagram, it won't load that way either and on the left-bottom of the screen it will give an error 'A register is empty'. Nothing has been changed on the computer system. I can connect to it and control it through lab advisor. Any advice/ideas?
