Can't import .npm file in to Password Mgr in Norton Internet Security 2009's Idenitity Safe

I am trying to import a Norton Password Manage file (.NPM) into Norton Internet Security 2009's Idenitity Safe. The NIS2009 installation is on a new hard drive. I backed up the old file before replacing the hard drive.  It created a .npm file but when I try to import it, I am not having any luck. Please help.
