1. Here's what it means

"Your License Key is not valid in this region" means that your License Key is only valid in a certain region, and may not be used outside this region.

1.1: To resolve this problem, please use Lumion on a computer that is located in the valid region.

1.2: If you are already located in the valid region, please make sure that you do not connect to the internet via a proxy server or other methods that will conceal your true location. Please visit this website to find out if you are accessing the internet via a proxy server (VPN).

1.3: If you are located in the valid region and do not access the internet via a proxy server, please post a new topic here at the Lumion Support Center or click here to contact your local Lumion reseller.
