I am find a lot of 0 byte files created by this application and when using it is a large production environment and expecting the application to be reliable, it can be a problem. I actually have had to create a file watcher program to watch for when this application generates a corrupted/ 0 byte file and delete and flag for the document to be reprinted. Your feedback is appreciated
are you using the latest version, and does it seem to happen total randomly?
Have youi activated the logging in PDFCreator?
