FM9 Saving Book as PDF crashing

Hi,

I am trying to save FM9 books as pdf files. It works occassionally but fails most of the time - usually at Pageblock 13 each time. The egg timer stops but I still have the "Opening CMM_Pageblock13.fm" showing bottom left. Then when I click on anything within Famemaker to navigate, I get the "Internal Error 9004, 8680130, 7515574, 8121681. FM has detected a serious problem and must quit" error message.

I've tried the "save as pdf" and also the "save as" and selecting PDF file.

I have gone into Print as a pdf file, clicked on the PDF Setup button, selected set and that also failed

I'm using windows 7 Ent with SP1 x64, Adobe FM 9.0p255, Acrobat standard 9.0.0, Acrobat distiller 9.0.

Can anyone help?

Thanks
