Which version of Word, and what is the data source? If your copy of Windows
is updated automatically via Windows Update/Microsoft update, some recent
updates ahave caused a lot of problems with Word.I quote CIndy Meister:

"There are massive problems with the most recent set of updates. There's a
KB article (http://support.microsoft.com/kb/918165) describing a workaround
for
some of the problems. But other people are finding they need to uninstall
the updates, especially MSO06-015."

Mail merge files and the data file I have used for sometime suddenly are
not
working. The word file cannot open the data source. It's like something
is
lost.
