Minecraft grad bought but it does not work. What to do?

A while ago I thought, why not download Minecraft and play n Bissl? So I made a profile with Mojang, bought and downloaded Minecraft, but when I wanted to play it, it was clear that only the demo version was available. I've checked out and logged in a few times, but that did not help.

Who has a plan what to do now?

Go to this link here: https://my.minecraft.net/de-de/store/minecraft/#owned

Should look like this then

Looks like that to me, I'm just about the third or fourth time to download it. ^ - ^
