I'm probably to late for my advice to help but maybe in future - Have you tried opening in wordpad? Sometimes that worked for me when transfering things between home and school, as usually they were different versions of Microsoft Word and for some reason it just encoded the text differently and would be all messed up when I got to school...

Also when I had something to take between the 2, I would save one version just in normal word, then i'd save another copy into Wordpad which always worked on any PC
