What do you do if you upgrade to a new computer? Does that mean you cannot use the free version?
You can use the Free License, just deactivate it on the old computer before migrating. You can do that in Menu > Help > License, then click on the deactivate button.
When you are all setup on the new computer, use Menu > Help > License, click on activate and paste in your activation key.
