1.1: A user wants to know why Lumion (any version) does not allow them to type in their License Key number as a quick way to update their license. 
Hi 
Thank you for getting in touch. I'm sorry to hear about your issue.
Unfortunately, Lumion Trial and Lumion Pro are two different applications. Your Pro License is embedded in the installation files of Lumion Pro and this means that you cannot input it in the Trial version.
In order to get Lumion Pro to work, please do the following:
1. Uninstall the Trial version.
2. Get the Download Manager from the 'Getting started with Lumion' email for Lumion Pro.
For your convenience, I have re-sent you the email to this address: ###registeredaddress@domain.xx###. Please check your spam/junk folders in case you can't see the email in your inbox.
3. Download the files from the link in the email and install Lumion Pro. Please note that Option 2 in the email (see screenshot below) allows you to directly download the files without having to create or log into your Lumion Account.
 
4. If you use Option 2: Direct Download' then please don’t forget to go back to Option 1 and create your Lumion Account, as that will be the go-forward provision for accessing Lumion updates, forums, and other services.
Let us know if anything is unclear. 
3.1: Ensure you change details for ###registeredaddress@domain.xx###.
3.2: Adapt the Reply: associate the License Key type to the reply, for example, if they have Lumion Normal or Student instead of the Lumion Trial.

4.2: User Question:
When I enter lumion, I can either proceed to "trial version" (which is not a complete version) or "buy a license", but I cannot use Lumion Pro with my own Pro license and all contents. When I shut it down and then restart it, the same happens. I´ve downloaded it from my account, in the button next to the license number and it says that this should be automatic, or that the program would ask me for a code, which it didn´t. I need to use it with my Pro license and all due resources. Thank you.
