How can I redeem my free GTA San Andreas?

According to this announcement, I downloaded the launcher and when I opened it, I found out that GTA San Andreas is not for free. What am I missing? and How can I redeem it? Thank you,

Update : I'm already over 18 years old. I don't have issues like a bug or an error. It's available but not for FREE as they claimed on their website.
