CnC Generals asking to sign in to EA account

My Father has been unable to play this game due to this issue for the past 6 months. The game loads up like normal, but after a couple of seconds, it tells him to sign in again with his EA account and fails to log him in after he puts in his correct username and password. Are there any solutions to this? My father all but gave up on trying to fix this. This game is his favorite, and he has been really bummed since this issue occurred. I need my Battle buddy back!
