This QuarkXPress processing message appears if QuarkXPress is unable to open a temporary file which should have been created during processing (CSV, RTF, or Templates Header file).
This internal error could be due to an overly aggressive anti-virus, or to Windows being almost out-of-resources. You should try to re-boot your computer. If the problem remains, please send the script to technical support, being sure to mention the error message ID listed at the bottom of this topic.
