Some people (like me for instance) don't see any ads so the response to view the ad above someone's post isn't very useful. Here's a link to a free on-line converter: http://www.pdfonline.com/pdf-to-word-converter/
You can use such a software for converting PDF to MS word or Ms word to PDF.I included a site for you where you can download this types and many other softwares.It's really a good site.
