enter link id after logging in

Hi. so I got a new pc and got the game, but when I started it I didnt enter link id and now I cant find a way to link my account. is there a way to do it? or maybe I can delete account and start over? anyone got any ideas?

As long as you use the same account you used to log in before, you can just continue where you left off. You don't need a link code if you use the pre-existing account
