Error creating Paromount + account in Spain

I've been trying to create a Paramount + account for half an hour. When I click in "Agree & Continue" after putting my personal data to create the account, it always says: "Sorry, there was an error creating your account". I wanted to pay a subscription to support the official launchment of Avatar Aang: The Last Airbender, but I just can't. I already hated Paramount for everything they've done to Avatar. But even when I was going to pay instead of watching it for free, they are not even able to allow me to create an account. At this point I think I juat give up.

Anyways, if anyone has the same problem in Spain or Europe, let me know if you find any solution.
