cannot activate SDL Trados Studio 2019

Recently I reformat my computer and reinstalled SDL Trados Studio 2019.

Installation was successful but in the activation step, I get the error message stating:

"could not activate this license. no licenses are currently available for the specified activation code."

I copied the activation code from my license page, which is not expired.

Could you help on this issue?

Thank you in advance.
