Hello and thank you for choosing JUSTANSWER.com
Are you trying to register Pinnacle Studio on a Library computer?
In some cases you may want to update your product registration information. The most common reason for this would be if your email has changed since you originally registered the product. As product registration and activation keys are tied to one email address, we strongly recommend that you update your email address before reinstalling your software or regenerating your activation keys. It's important to update your profile and not to create a new account with your new email address or you will not access to your registered data and activation keys.
