Cannot log in from within Trados Studio 2021 with my usual email/password that i use here


I need to download a compatibility pack from the Appstore but i can't log in from within Trados Studio. I'm using the same email and password as i always have, but i get an error message stating that my SDL ID isn't linked to any SDL Language Cloud account and i must create an account or contact my admin (but i don't have an admin, i'm a freelance translator). I already wasted so much time trying to figure out this, could someone help me out? 

Many thanks!
