Can't seem to change Default settings for Autosave

I originally installed PDFCreator some time ago, but we never used it.  Today we had an application which needed it, so I updated to version 1.2.3 and set things up. I changed the setting for "Use this directory to auto-save" to a different directory than is was originally set for, and saved it.  Problem is, whenever I close the PDFCreator PDF print monitor, it reverts to the old directory for auto-save.  What am I missing?
