This happened before and I was able to get the systems back somehow, but forgot the methods I used. I set location and loaded the DB the first time after programming, but I don't want to monitor the whole DB. When I turn off the DB and go to 'Systems To Monitor', some have been disabled and no option to turn back on without turning DB back on. I know it's a simple fix, just not very savvy with the menu. Thanks for any help.
