For anyone who used SE to buy the game online, you have to go through your email and look for the "Order Comfirmation" email from them(should be one of the first emails you got from them, sender for me was "webhelp.v4"). Then go to "Find My Order" and log in using your Order Number (In email) and your SE account password. The code you need should be under your serial code. Then open up the game launcher, select "I already have a SE account", then up the serial code in. I'm saying this because, although this helped, I didnt order from amazon. (Sorry if this is a repeat of someone else)
