Microsoft Office 2003 and 2007 crashes when managing EMF (enhanced metafiles)

It is very strange and I'll try to explain it as well as I can.

I work with Windows XP, and Office 2003 (Office XP, I think). All of
them are official copies, "genuine software", as Microsoft uses to
say.

I never had had a problem like this one.

I use MS Visio to build some vectorial graphics, which include some
text. Then I save it. I have worked with those files, copying the
graphics, pasting them as a Visio object, as a EMF file, etc. I have
pasted some graphics originally produced in this way as EMF files in
some Word documents.

Everything worked OK. Then, I do not when and why, Visio has started
to crash when I try to open any of those documents with EMF files. In
fact, I created a EMF file from one of those vectorial graphics, and
Windows is unable to open it with the default previous-viewer -well,
it opens it, but it doesn't show anything.

Also, when I open Word documents which contain EMF images previously
created with Visio, images no longer appear, but a blank rectangle
with the typical symbol for "image not found" at Internet Explorer.

That was at Word 2003. Now, I upgraded to Office 2007 (also genuine
software), willing to get the problem solved ("install a new version
and everything will be cleaned", I thought). The only thing that I've
got is that, now, Word also crashed, when trying to open one of those
previously mentioned documents!!!

One of the times Word crashed, when I relaunched it, it told me I had
two documents that had been recovered from the crash. One of them was
my document (with EMF images and so on). The other one was a strange
document called something like "building blocks", or something like
that. I am no longer able to reproduce that situation, but I remember
having seen that.

Obviously, as Doc would say (Back to the Future) I did something in
the past that has changed the way Office/Windows manages EMF files,
and that causes that kind of crashes. I do not know what it was...

The 'only' thing I would like to know is: Where/how can I "recover"
from that error? How can I repair the "place" or "thing" that Windows
and Office use in order to manage EMF files? I mean, I suppose there
should be a program or a process that is responsible for this...

Thank you for your kind help. Please, ask me for more details, if
necessary.

NOW IS EVEN WORST:

I've unistalled Office 2007 and then I've installed again Office 2003,
and now, when I open a Word document and I write in it, Word
disappears!!!

Even with a brand new document, I write something, and Word crashes
(in that case, it allows me to send a message to Microsoft and offers
me to go to the Office Update site, at least...).

I do not remember having seen this since the ages of Windows 98... :-

Perhaps explain "disappears"
Presumably you've run Detect/Repair from Word>Help?
You've examined event logs for any clues?
