Have Publisher 2000. But it won't let me open a .pub file Why?

[dc.petersen1]

I just loaded MS Publisher 2000. I am trying to open a .pub file, but the
system gives me an error "Publisher cannot open files from a different
version" What does this mean? Why can't I open a .pub file?

Because the file you are trying to open was created with a later version
of Publisher.

=========================
What version created the .pub file?

If you have Norton, disable "script blocking" and in Norton options, misc. disable
"Office Plug-in." Publisher 2000 cannot open documents created in Publisher 2002 or
03.
