Can't launch Dragon Age II from EA app

Hello,

When I try to launch Dragon Age II from the EA app, I am prompted to sign in to my Origin account to activate the game. However, Origin shut down earlier this year, so I cannot login or create an account. When I cannot log in, I get a message saying I cannot activate my game until I login to Origin. This makes it impossible for me to play the game.  How do I solve this problem? 

Thank you, any help is greatly appreciated!
