Reilli,
You don't need to re-install ZFD, just take a copy of the snap-in's directory under sys:\public\mgmt\consoleone\1.2\ and copy to your local machine.
To see whether ZFD is installed correctly on teh server, type in java -showall at the system console and verify that the services (AWimport etc) are running. If they are, it is more than likely that your ZFD installation is correct
