We provide the demo for free on our website so I'm sorry if someone had you pay them for it. If you have also purchased the digital download edition, you simply need to start the installer, enter your product key (provided in the email confirmation of your purchase) and proceed through the steps.
You can download the latest installer here or follow installation instructions in the manual.
