Auto-save directory resetting to default issue

Hi,

 

we've been using PDFcreator for a while and it's working fine... however lately an issue has come up.

My auto-save path is for instance c:\\pdf

The last 2 weeks the program changed this folder to c:\\pdf\\pdfcreator without any user interaction.

Does anyone know why this happens and how it can be prevented? After the creation of the PDF more batch scripts run to move/copy those files... and everything stops working.
