Can't download assets from the store. Please help

Hi.
I’m bloody new to Unity and want to get started with my first project with the help of some tuts on youtube.

The example I found needs an asset to start.
But I can’t download the asset or another one.

The download button is never clickable.
I have already disabled all firewalls, but I can’t download anything.

What can I do?

Open Unity and head into the Package Manager (accessible via top menu > Window > Package Manager). You will find your Assets (paid or free) under My Assets.
