It appears that you might have updated your executable and not your ado-files.
In the 15dec2003 update, we moved the internal -merge- command to -_merge- and
wrote an ado-file wrapper (merge.ado) to call _merge.  This change was made to
allow merges with multiple using files.

I would recommend typing -update ado-.  After that, try again.  If you are
still having problems, I would then recommend that you contact Stata Technical
Support so that we may further investigate the problem.
