Do you have backup copies of all these chapters?
If not, you run the risk of losing a lot of work if your hard disk fails, or some other catastrophe befalls the system. Don't create just one backup copy, create two. If you do lose the originals, then that one backup copy becomes the original and you have no backup.
Sorry to start off like that, but we see horror stories in these forums and elsewhere where people have lost years of work.
Next, I don't use Word 2007 myself, so I don't know what it is like, but I would try this. I would recommend you make 'further copies' and work on those. Don't work on these originals, nor any backups you have. That way, if you make an error or anything goes wrong with those files, you just delete them and start again on fresh copies.
Also, I would move those copies to another folder and work from there. It avoids selecting the wrong, (original), files in error.
I assume you created some of these chapters in a previous version of Word, then moved onto Word 2007. Is that right? If not, what do you mean by they reverted to a previous version?
If that is right, then try re-saving one of those 'reverted' files in Word 2007 format. Open the file, quick check through, then re-save it using "Save As" and not Save. In the Save As dialog, make sure the "Save As file type" is selected to the one of your choice, eg .docx, or whatever.
Then, close Word down, re-open Word and open that file you have just re-saved. Try a print and see if it is OK now. If so, repeat the exercise for the others.
Does that help?

I recently finished writing a book. After I finished, I went to print out the book (each chapter is in a different file) and I noticed that some of the chapters had reverted to an older version, while others remained with the correct version. This has continued to occur, with what seems no rhyme or reason.
I initially thought that it must be a hard drive issue. I ran Western Digital's hard drive diagnostic test for my WD800BB hard drive. Both the SMART test and the extended test (tests all blocks) came back as "passed" with no errors whatsoever.
My next attempt was to run Malwarebytes AntiMalware, Spybot, and Norton Antivirus 2010 in order to find any malicious software on the computer. All of these tests came back without errors.
I am now stuck; I am not sure what the next step to take is. I would appreciate any input on the matter.
I am using Windows XP Professional SP3.
