That's just a generic error telling you that Qimage has developed a brain tumor.
Translation: one of your startup (INI) files is corrupted. Assuming it's the main one, you can clear the problem by starting Qimage while holding the shift key. If that allows you to start it, you can go from there and set whatever settings you like. If you have the Qimage.ini file backed up on a backup somewhere, you could always try reinstating an older version of the Qimage.ini file (into the Qimage application folder) to save you from having to set your preferences again.
Between Fred's email and that suggestion, hopefully you'll be back up and running.
