When I tried to open the document, Word reported that it was damaged. I was able to recover the content (see attached file), but you may have to do some reformatting. 

If you want to keep different headers and/or footers, you probably have to recreate them. For reference, see http://wordfaqs.ssbarnhill.com/FrontMatterRibbon.htm.
