The password uniquely identifies your license. You will need the password if you ever need to reactivate your software (such as after a disk reformat and reinstall or moving the software to a new machine). We suggest you do not use one of your important personal passwords for the activation password or a password that personally identifies you. The password has to be changed and be new (never-used) each time you re-activate the software.
We suggest that you write the password down on your activation code label (box or CD case) or in some other permanent location.
