I wish they'd put the serial number inside the CD folder, like Adobe does. I put a yellow sticky inside my CD folder so I would find it easily. It might actually be better to type it out on a mailing label and stick it inside the CD folder. Or even better yet, also on the CD itself. I'm always afraid of losing it. I think I also stuck a copy of it inside the Manual cover. It would be a nightmare if I had to reinstall it for some reason and couldn't find the serial number. I would go into severe withdrawals, that's for sure. ;) Melanie
