I have just bought one copy of the game normally for myself, and i am trying to buy another one for my friend, but when i click on “buy digital deluxe” or even " buy normal version", nothing happens anymore? It was working literally 10 minutes ago? What happened?
He is also trying to click it, but nothing happens as well. Tried different browsers. We have different IPs…
Anyone ever encountered this?
We have a temporary glitch. Would you be willing to try again? I just got the “all clear” email. 
Oh shucks. I was hoping the fix I saw in the email would make everything work just fine for you.
Could you please contact Support by filing a ticket through the “Ask a Question” tab on that linked page. They will be able to assist you. For tips on what information to provide in a ticket, please read this post.
Also, if any of you guys in this thread have been able to buy, could you please let me know so I can get an idea of the scale of this issue? Thanks.
