TM (button) not activated in Trados Studio 2021 freelanceplus after the version upgrade from Trados Studio 2021 starter.

Hi!

Recently, I subscribed to Trados Studio 2021 starter. But I found many functions needed are not offered in the version. So I upgraded the version to the Trados Studio 2021 freelancerplus.

TM button is not activated, and it is colored gray. When the button is touched, the following message shows: " your license must be upgraded if I want to use this function(in Korean)." 

Please let me know what's wrong with my use of the Trados.  

Have a nice day!
