Activate key not valid after a new installation of Windows 11

[VernonSubutex]

Hi👋🏻

a few days ago I reinstalled Windows and fs2020. When I want to reinstall gsx pro I have a message that says "Using a QLM key, the activation server returned. The license key XXX XXX XXX XXX is invalid. Please enter a valid license key".
I copied and pasted the key in the purchase confirmation email dated 08/20/22.

I think the key is only valid for version 2 of gsx pro.
Before reinstalling Windows, gsx pro was installed in version 3 so the key was active.


How can I find gsx pro without buying it again?

First, go here and try the e-mail license key option. If that doesn't work, try de-activating the license that way.

Small feedback regarding my activation key problem after a new reinstallation of windows 11.
I had to deactivate my 6 licenses already used from the site and then reactivate with the FSDT Live Update installer.

Thanks you for your help @Captain Kevin

Yeah, I figured that might be the issue. What happens is a lot of the time, people either don't de-activate their licenses before re-installing Windows, or they have a hardware failure where they can't de-activate it, and generally, you only have a limited number of activations per license. In the case of FSDreamteam, though, you can de-activate it yourself even after the fact if you needed to. With other developers, you'd have to get in contact with their tech support, and that can take time.
