DOCX with Equations Wont Open

[Professor]

I'm writing a book in Word 2007: it has many equations (using equation
editor) and inserted objects such as power point slides.

Today I couldn't open one of the chapters. No changes were made to the
computer (which is virus free). Word declares it cant open the file and must
send this error message:

AppName: winword.exe AppVer: 12.0.6504.5000 AppStamp:49e7f5b6
ModName: wwlib.dll ModVer: 12.0.6504.5000 ModStamp:49e7f5f9
fDebug: 0 Offset: 002b4d36

Can someone please advise me? It seems that word becomes very unstable if
there are too many equations and objects. I've tried the usual suspects:
autosave, wbk etc. Nothing works. Is it time to switch to Latex? I hope not
-- word is convenient.

wwlib.dll problems are usually because you have an incorrect version of the
..dll. Something must have changed that dll on your computer. Try rollback
and see if that restores the correct wwlib.dll.
