This makes me think its a windows thing but who knows.
'If your error message is : "Acrobat PDF File Format is having
difficulties", this problem is documented on Adobe Web site :
http://www.adobe.com/support/techdocs/26b3e.htm
It's due to the use of accent, bullet or umlaut in your Illustrator file
title.'
So there you go, same problem.
