Your purchases are still available. They are in the deprecated section when you click on the "All My Downloads" link from your account and scroll down to the bottom. Your most recent purchase was over 7 years ago, and the vast majority of your purchases were almost 12 years ago. This means most of your products will not work in the latest version of Dreamweaver. You would need to use CS6 or earlier versions for support of your deprecated products or upgrade to the most recent versions to work with Dreamweaver CC.
