Upgrade Broke Mail & Address Book

[ChrisKil]

In going from Tiger to Leopard, I backed up my HD to an external, but I apparently didn't do it correctly because Migration Assistant acted like the files were not there. So, I manually copied my files over along with select apps & preferences files.

I got everything (Firefox, Thunderbird, etc) working exactly how I left them in Tiger. But, I messed up my Address Book and Mail. Now when I try to use them it says "You cannot use this version of the application [app name] with this version of Mac OS X.

Is there a way to just reinstall these two apps without starting over with a fresh install?

Mail is considered an optional install, so you can just run the Optional Installs bundle on the OS disc. Address Book is part of the core operating system, Pacifist may allow you to reinstall from the Mac OS X Install disc without doing an entire archive and install.
