Hello Valerio Palmieri

What kind of internet connection are you using? 

Do you also use a docking station?

Thank you,

Sorin

Hello Roberta Palmieri

The licensing system used by Studio generates a unique Installation ID with each activation of the software. This ID is created based on 2 criteria: Disk ID of the PC and the Ethernet (MAC) Address. 
When using USB Tethering internet connection it generates a random MAC Address. Because of this, when you launch Studio, the software believes it's a new installation (PC) and, for safety reasons and to avoid fraud attempt, does not allow to use the license code. This is to prevent to use the same code on multiple PC`s.

I`ve reset your license. Please try to activate it while connected to a Wireless network and normally it should work if you use the USB Tethering internet connection afterwards. 

In case it doesn`t, the only solution is to deactivate the license before shutting down your computer and reactivate it when you open it.

Starting Studio 2021, the Ethernet (MAC) Address will not be used for the license activation anymore so this problem will not occur anymore. 

Thank you,

Sorin

Thank you so much for your help! I've just activated through wi-fi and it seems be working!

Many thanks!
