If you ordered from Amazon you will NOT get an email from square with code. If you log into Amazon and go into "Your Account > Your Games and Software Library" It will show a listing of all of the games have ordered and any keys associated with those games. You might have to click on a little yellow button that says display key. I can't remember what it exactly said but it was hidden under that button when I logged in for the first time. The code that you find on there is the one you need to register. If you didn't order from Amazon but still bought a digital copy then the code might be on the website of the retailer you did purchase it from. I hope that helps!
