My computer will no longer make Word docs into PDFs; It was working fine until I was converting a big Word doc to a PDF. I'm using Acrobat 8.0 Pro on Windows 2007. Says missing "AdobePDF.dll" file. How do I fix it?

Did you upgrade WORD since it worked? If so, that is likely the problem (and you will either have to print to the Adobe PDF printer or use the WORD built-in converter). If you have not upgraded software, then open Acrobat and go to Help>Repair. That will hopefully fix the problem.

What's "Windows 2007"? And Acrobat 8 is a very old version, not supported any more and not compatible with any current version of Windows or Office.
