I am using Snow Leopard 10.6.6, Office 2011 and CS5.
If I go Print> Save as PDF the pdf is readable by Preview, but crashes Acrobat.
Preview can read the PDF and if I open it in Preview and go Print>Save as Adobe PDf the resulting PDF is readable by Acrobat.
Trying Print> Save as Adobe PDF directly from Word crashes the process.
Excel and all other applications that I have tried create PDFs that Acrobat can read.
Any ideas?
