I have tried on the web, it just say something's wrong. I have linked my CC too. I tried on the console and same error.

Sign out and in again. Do you try in your Xbox Live account main region? Are you there (I mean If you have US account you should be in US)? I got this message if I tried to download games from US region (my account is in US region), but I'm outside of US, so it's region locked, that's why it's blocked.
So try to download from your Xbox Account's region store or from the country's region store where you are now.
