Trados 2021 re-installation after repairing my computer

Hi, my name is Daniel Kim, a translator based in Republic of Korea.

I'm using Trados since 2011 and later upgraded to Trados 2021.

Recently I repaired my computer and tried to re-install Trados 2021 via Online Activation.

First, I logged in to my RWS account and downloaded TradosStudio2021SR2_16.2.10.9305.exe.

Then a trial version of  Trados 2021 was opened.

In the activation menu, I copied and pasted my SDL Trados Studio 2021 Freelance  activation code xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

But it says,

"Activation failed.

Could not activate this license. No licenses are currently available for the specified activation code."

Please help me out with this issue.

Thanks in advance.
