Autosave dwf


I've been using PDF Creator for a few years to batch print autodesk .dwf files into PDF's.


After recently upgrading to windows 7 and Autodesk Inventor 2011, printing .dwf files works erratically.  It will not save all the PDF files, typically 4-5 only out of a batch of 20.


The auto save file name function will not work either.  Whichever file name token used, it will still name the pdf's as

I__~Rigging Projects_~Jobs‹##‹44 - V&A_~Engineering Drawings_MFT Issue_MFT 01 19-07-10‹44-E92002.pdf


we used to be able to simply auto save as 21344-E92002.pdf


Can anyone help
