I have 1.04 installed on my Macintosh, and I stopped using it as I wanted an email program that had more features, features similar to what you find in MS Outlook. And I never could get the filters to work.

I left 1.04 on the computer as occasionally I would access the address book for information. But somewhere along the line, it has quit working. It simply hangs up during startup. It may have been a casualty of upgrading from Leopard to Snow Leopard.

I need to access the address book again.

If I reinstall 1.04, will my existing data be retained? If not, what files do I need to copy/move/protect/ whatever?
