Greetings, Paradox Devs!
Got my expansions registered, and I've sent an email with the requested documentation of my faulty COMS key to your eu3code email address. Just letting you know that you've got another key request waiting for you in your inbox.
Got the core game in the summer sale, so my faulty COMS key dates from then. Only ran into issues when I tried to register on the forums recently after snagging the expansions-- found this thread and here I am.
Your help would be appriciated.
