If anybody loses their password and they use version7 they should add a new user with a password that you know. Then open the database and go to TLBAUTHOR table. Find the new user you added and copy the PASSWORD and then the SALT of the new user and past them where the current password and salt is for Administrator.
If you copy just the encrypted password it will not work. You must copy that password and the salt. Hopes this helps someone as my Administrave password became corrupted when I upgraded to 7.
