ROES Server - Won't Launch - "Unable to start ROESEngine:\n\nCan't start application"

This is usually caused by a corrupted xml file in the 'Printers', 'Queues' or 'Workflows' folders.  Use your backup of the .ROESServer folder (or similar folder name ROESSAS, ROESSAR, etc..) and replace the files in the current folders with the ones from a good backup.

If you don't have a backup, you will have to recreate the printer/Agent, Queue or Workflow
