Hey... @Ian3697

You can connect on your other profile because it is linked to your EA account. 

The steps required to link your other account (the one not connecting) to your EA account can be found here: https://help.ea.com/article/linking-your-gamertag-psn-id-or-ea-classic-screen-name

You may be having trouble importing your XBox Live Gamertag or Playstation Network info if it is linked to an account other than your main EA account.

To recover or make changes to your XBox Live Gamertag or PSN ID, be sure to contact an EA Game Advisor : http://help.ea.com/en/contact-us/new/?category=demo-beta
