it depends on what version of Symposium you are currently on, a new keycode has to be purchased (one that matches the Dongle Id of the Option 61C) this keycode is then used on the Symposium Server, (each release has a different routine to change the keycode, routines are available for Release 3, 4 and 4.2), the server should be backed up first and the new keycode entered, a reboot is required to activate.
