Help with Help

VS03 ("pro" academic, I believe) is on my home and work peecees, along
with the MSDN that came with it.  One persistent problem I have is that
calls for help from the IDE often produce a dialog asking for a file at
a place different than what I have.  MSDN for me lives in

c:\program files\msdn\2003feb

but this dialog wants d:\program files\msdn\2003jan.  I've done the help
(documentation) update which at one point I thought had helped.  But it
seems either not to or to have degraded.

Any ideas how to get this thing pointed at the right set of files?

Thanks much.
