Returning player can't access old account

I would recommend 2 things. First you picked a poor day to come back, many users, myself included have been having major login issues for the past several hours. You might want to give it a day or two and check the forums here to see if those issues have been resolved. Second try on other devices if you have them available, my login is working fine from both an Android phone and iPhone but not my preferred tablet. There is also a Windows app now available in the EA launcher. You might try and see if you can access your older account through Windows or another mobile device while they get the current mess sorted out. Best of luck and welcome back.
