Thx Mikey & Bob. Got it to work using ur tips.
One more thing that hasn't been mentioned is that you create an entire new account (registered email address) don't just use the default User1 account provided on the base console. I was able to log into the editions button with a 'User1' account / my main account on a player 2 controller - however this would not unlock trophies. Fresh registered account / main account on 2nd controller allowed trophies to unlock.
Hope this helps
