Anyone else have recent connectivity issues between Office 2004 (Mac) and X1? Bad MS patch?

Within the last couple of weeks, Endnote stopped communicating with Word.  Another colleague of has the same problem now too.  I had to reinstall Word, do all of the updates BUT did not do 5/18/08 update(!!!) then reinstall Endnote.

Is the 5/18/08 Microsoft update the issue?  My hypothesis is that it may be affecting the function of Visual Basic Editor in Word which is needed for Endnote to work properly.
