Plugin purchases made prior to mid-2021 were stored in a legacy system which has now been deactivated. There is no requirement to re-register plugins in the current SSL Account portal, since all licenses are stored securely within your iLOK account. You can view your licences by logging into iLok License Manager, or online by logging into your iLok account at iLok.com.
All plug-in purchases made in the current SSL web store will automatically appear in your account. During the checkout process, you will be asked to enter your iLok username; licenses will be deposited to the nominated account immediately.
