Studio2021 Freelance Plus Extra Activation Issue

 Previously had extra activation and used just fine on  Laptop and Old Desktop.

Now the extra activation disappeared when I installed Studio 2021 Freelance Plus on a NEW DESKTOP! What is up?

I downloaded the Studio 2021 SR1 on my new Desktop.

Deactivated studio on old desktop.

Tried to reactivate on new desktop.

Error said 'No activations available for the code provided"
