David, I have this software from a previous giveaway. In the website when you look at your “Software Licenses” you will see a column with a tag “Available until” and a specified date. That means you can download updates only until that date. After that you can’t download the software anymore. But if you see something like “Secure-PDF Professional – Private license” in the “Description” column in the website, you have a full license for unlimited time.
