That can be a real bummer if you had jobs in there on hold like cut jobs from prints that have not yet been laminated and cut. I know if you have the machine itself selected on the left side and you happen to hit the delete key, it just deletes the setup (along with its jobs) which can be quite irritating. That being said, look around on the computer for the Flexi temp folders where the actual jobs are stored. They might still be there. Copy them somewhere else then go back in and add the setups back in, then if the jobs don't automagically show back up try copying the files back to the new temp folders and they might show up and work.
