PDFCreator: 1.7.3 - incorrect content



using the above mentioned Version of the pdfcreater in Microsoft Dyn. Nav 2009 to created pdfs via batch.
The pdf creater is used to create pdfs based on a report result.

The creation and printing pdfs is running in a batch of max 500 prints. It has happened that the content of the pdf file was mixed up. For example it took the content from another report result inside the batch and saved it with the correct file name and path.

I'm aware that we are using an old version of the creator but maybe someone else had simular expierence in that past and could share it?
