Restoring a License
Version 5, 6, and 7 use a file whose name ends in rrg. If you have backed up the file on a floppy, you can use Help in the program to restore from the file. J. River does not issue replacement licenses for these.
Version 8 and above use a web based database. You can recover your license, usually by using the Registration Code you received by e-mail from buy-button @ jriver.com. You can enter it on the Restore Page.
More details can be found on the Purchase FAQ page.
