Address a problem with Microsoft Word 2002

[moti]

Hi

I have windows vista with word 2002.
Recently when I'm trying to open word document, I get the following error
message:

Address a problem with Microsoft Word 2002
Microsoft Word 2002 has stopped working properly.
This product entered its "Extended Support" phase on July 11, 2006. For more
information about Microsoft Corporation support cycles, see the additional
information section.
Consider upgrading to the latest version of Microsoft Office to receive full
support.

Does someone know what the problem is? how can I solve it?
I don't want to upgrade my office yet.

Thanks,
Moti

Is that the complete err msg?
Does Event Viewer report anything more relevent?
And if you start Word, then open a doc?
Tried Detect/Repair from Word Help?
