Where did you buy the game?

Make sure you typed the code right. The following letters look very similar and are easily mistaken for each other

• 0, O and D
• 8 and B
• Z and 2

Hi 🙂

You can try to redeem that code from Origin <My Library <Add new game!  Works for me 🙂

I bought it from Argos brand new, I checked over it several times but it still won't work ☹️

I'm starting to think I've gotten a faulty code (Just my luck XD )

@xgamesworld Hi! 🙂

I've tried it but it still doesn't work, thanks anyway 😉

I'm starting to think I've been given a faulty code X3
