Part of the problem may be that there are two different equation editors in
Word 2007. The older one, Microsoft Equation Editor 3.0, has to be
specifically installed (it's in the Office 2007 installer but not selected
by default) and invoked through the Insert > Object button. This is the only
equation editor available in Word 2003.
The new one, which is available only in Word 2007 (and now 2010 beta) and
has no special name, is invoked through the Insert > Equation button or the
Alt+= shortcut.
Which editor was used in Word 2007 to create the equations?
When you save a document containing equations of the new kind, they're
converted to pictures for Word 2003, even if you have the Compatibility
Pack. However, the document should still be able to open in Word 2007, and
(after using Office button > Convert if necessary) the new-style equations
should be editable again. I suppose it's possible for the conversion to
damage the equation data in the file, but I've never seen that.

Until this document I never knew there was a new equation editor. I only
got Word 2007 a couple of months ago and when I was using equations, I was
generally editing equations either in old Word 2003 documents or copied and
pasted from old Word 2003 documents. When I edited them in Word it seemed to
use the older equation editor (I assume it got “selected†the first time I
used it). However, early on in this document I had to create an equation
from scratch. I used the insert > equation button. When I found out how
easy it was compared the old editor, I stopped copying and pasting equations
done with the old equation editor and just used the new one more or less
exclusively (to my current regret).
The document will not open in either Word 2003 or 2007 (I still had Word
2003 on an old laptop I don’t normally use anymore) but when I used that link
in my previous post to convert it to a doc file, it does open in Word 2007
but with the equations done with the new equation editor gone. I suppose I
could try opening the file converted at the link with the Word 2003 on my old
laptop.
Perhaps it was a bad idea to have equations created by different equation
editors in the same document. If so, I can avoid the mistake in the future.
However, right now, I would really like to savage my work.
