Thank you for your feedback.
As mentioned by Shareware Team this product (personal edition $29.95) is fully free for lifetime.
It recovers all the license keys as mentioned on giveaway page. Upgrade is not required to recover more license keys. If some application key is not found please write to our team (firstname.lastname@example.org) and we can help you recover the product key.
Upgrade is needed only for (Enterprise Edition) advanced features like recovery from external disk, registry file, remote computer, command-line version etc.
