Comunque chi ha fatto una donazione precedentemente non deve pagare alcunché per detto aggiornamento (e per successivi, almeno fino alla versione 4.0):
If I paid for CCC in the past, am I going to be asked to pay again?
No, if you paid for CCC in the past and checked the "I paid" button, this version of CCC should not ask you to purchase CCC again. If your preferences have been cleared or if you're using a different user account, see the next item to learn how to retrieve your registration information.
How do I retrieve my registration information? I paid for CCC in the past, but now I'm trying to use CCC under another user account.
If you see a prompt to purchase CCC or banners during a backup and you have paid for CCC in the past, you can retrieve your registration information at our website. Simply provide the email address that you used when you paid for CCC, and we'll send your registration information via email. A link in the email will instantly register CCC (no copying/pasting of registration codes, etc. is required)....
Updates (e.g. bug fixes, 3.5.1, 3.5.2, etc.) are always free to registered users. Upgrades (e.g. version 4.0, 5.0, etc.) that include new features and functionality, support for newer operating systems, etc. will be handled like most commercial software: current users will be offered a lower upgrade price but the previous version will continue to work if you decline to purchase the update.
