FrameMaker 10 not printing PDFs

When I try to print to PDF on FrameMaker,  I get the "printing book" dialog box but nothing happens....the PDF is not created and no errors are reported. If I choose to print to poscript, open Acrobat Distiller, the PDF is generated there.

I recently upgraded to FrameMaker and Acrobat 10. I didn't have any issues on 9. I'm currently running both versions of FrameMaker on my PC for now.

Is this a Windows 7 issue? My co-worker has both versions of FrameMaker running with acrobat 10, but on an  XP system and everything seems fine on his end.

Thanks,
