lost custom tables and reports

At home, I carefully craft a custom set of fields, tables, views, filters and
reports to suit my particular project plan and complement the built in ones
in MSP, and check in the Organiser that they are there, available in the
current project but not in the Global template, and then email the mpp file
as an attachment.
But, quelle horreur! when it gets to the other end, my address at my other
office actually, all of the custom stuff is gone.
I don't get it. Why doesn't it stick?
It does not seem to be a problem with the 2002 version at home and the 2003
version at the office, since even when I email it to myself and then retrieve
it immediately via webmail, the stuff is still gone.
Hope this is enough information. I am stumped.
