#58 Lost old mail during upgrade

[Anonymous]

Upgrading to 1.42 from 1.41 on jaguar (1.41 gave me the
not implemented error). Used the Installer, and ended
up with a new Hotmail mailbox, and lost any old emails.
It appears there are old files in
users/myname/Library/Mail/HTTPMail-myemailaddress@hotmail.com/Hotmail.httpmail

These files are in a different format from other
mailboxes, and can't be importedinto Mail
