Thank you for your reply.
I've been re-reading this whole thread.
Getting the Word files to your Mac seems straightforward - several ways of doing this were mentioned in post#2 - Dropbox, for example (free and cross-platform). The key is making sure that what reaches your Mac is unadulterated by whichever method you choose.
The problem, as I see it, is the interrogation of these files such that they can become useful (and editable) and you have shared your frustration with the various means you have tried.
Our Admin, chscag, has suggested Preview (that's the click-to-highlight and hit spacebar method), Text Edit, and I offered Pages (Right click on file > dropdown menu > Open With > Pages). Presumably, you've tried all of these without success? I assume the same goes for Apache Open Office?
If you are sure that you have access to the correct, uncorrupted files on your Mac (from your email, for example), and none of the methods suggested works; then the only thing I can think of is getting Office for Mac. This is not cheap, I understand that. It's a question of how important your project is. You mention in your first post that is a "large' file. There is also the horrid worry that Office might not work either, but if you can do all you want with the file on your PC, then this should apply equally to Office for Mac.
I'm sorry, I'm not being more helpful.
