What OS and version of Acrobat are you using?
If you upgraded to 9 and you have not opened Acrobat as yet do so it will give you the option to have Acrobat set this up.
I would then restart the computer.
If the option does not present itself I would uninstall and reinstall.
BTW you will have to first print to .ps then distill to get a pdf
To answer Mr. Schneider's question I am running Mac 10.6.1 and Acrobat Pro 9.1.3. I reinstalled Acrobat (9.0.0) and the problem is fixed. I believe that the update to 9.1 or 9.1.1, as they seem do more than update the languages, are the culprits causing the PPD file to become incompatible. Has anyone else had this problem and come to the same conclusion? Thanks.
Look over at the Acrobat forum where you will see that things have changed in the making of a PDF in Snow Leopard.
