I don't know what you did by "moving" from Windows 11 to 10, which might be fairly complex, but I assure you it was completely unnecessary, since GSX works perfectly fine with the Fenix and the PMDG in both Windows 10 and Windows 11.
You said you "exusted my lic 5 times", when reinstalling the OS you should have consumed only ONE, have you done this 5 times already ? Why ?
However, that's not a problem, since you can Deactivate on your own at any time, reclaiming your activations, and if you do it from the Self-Help site linked on the FAQ page of the site, you can Deactivate even a previous Windows installation or a computer you don't have anymore.
