I bought the new DLCs on the Paradox store and didn't receive any email.

As title states, I have no activation code or bill sent to my email.

Thank you.

Ok, nevermind, it just took a bit more of time; I still didn't get any activation code tho.

From what I understand, you get the code on Monday.

If you bought the Old Gods expansion, maybe you won't get the serial number until it's actually released.
