For Netobjects users who lose downloads or serial numbers, it is worth it to purchase the backup disk when ordering the Version 12 upgrade. Usually, I do not order backup disks. But for some reason I did this time. It comes with your serial number, name, company, and address printed right on the disk. Be sure not to throw it away when it comes in the mail thinking it's an advertisement. It comes from ask|net and not Netobjects.
