Help! My postscript file won't distill

[Rebecca.L.Frasure at aphis.usda.gov]

Every time I try to print a Framemaker book to postscript (or save as PDF) 
I get the message - This PostScript file was created from an encrypted PDF 
file.
Redistilling encrypted PDF is not permitted. 

I have checked all of the security settings and there is no security 
settings. What is causing this, and how can I remove the security 
settings?
Thanks very much for anyone's help!
