Is there any link may I download the game ?
as a new player you have to wait till the maintenance has ended
please refer to this thread : website maintenance
once you've done it, you can download the game once you are a member of EA's battlefield.
( the download will start when you click on "play now" button. )
or if you want, you can start at EA as new account directly to play the game but by this, you cannot link it with aeria's account anymore i'm afraid
