I have the Ultra 7 package but what you have should do it. I believe
Nero Showtime should do it without any additional purchase. The pop-up window may have been a solicitation to upgrade to Ultra package. The serial number usually comes on the tyvek/paper mailing envelope.
There may be a problem with the disc you received. Try scanning the disc and e-mailing with an explantion to Nero.
Take a look at the following link: $5.99 for Nero w/ free shipping
