Minecraft Key activated but only a demo?

I bought a Minecraft Key and redeemed it on the official website. But when I go to the Minecraft Launcher and log into my account, I can only play the demo version. Maybe someone can help me there

Hmm So it could be that you made a wrong acc or you made code without 1007-then dash

So without - then it would look like this 4729-4658-3658-4735 that's right because my friend had the problem too and I too I hope I could help
