I changed my gamertag and now I can't log on to EA play or play any of the games

I have the same problem, but I managed to notice that I was signed into a weird account, log out and log in to my actual account, now I can't install/play any of the EA stuff, and without knowing the credentials I can't log back in, or unlink the accounts (to re-link to my actual account)

I am listed on my xbox as one gamertag, but when I try to log in on the computer it comes up with a generic gamertag. I can't change anything, and if I try to change the generic tag to my tag on the xbox, it tells me that name is already taken. Also, the
generic tag does not have any of the games that I play on it. I used to be able to log in with my old tag, but for some reason it has all changed.

that's unfortunate as that's now the only way i can play ea games online forevermore. I deleted my ea account months ago and that, according to them, is the only solution: new gamertag with new email address (even though a new gamertag will be associated
with the old MS passport address which is the email i used on ea's log in). No BF3 for me then.

I recovered my account on my uncles xbox and when I recovered it back on mine I can't connect to EA!! Iv been playing sims n it doesn't connect and NOW I just downloaded the battle field 3 beta and I can't play bcoz it doesn't connect to EA!! Is there away
of changing my EA account to a different one because iv just made a new one n I don't know how to make that ma new one to sign into when I play sims or any other EA games ... HELP!!

How are you, mate?
Try logging out of the EA Desktop app and at the login screen, scroll down a bit and click to log in with your Xbox account, and see if you can now install any EA games.

I have tried it before, nothing change. They offer me to buy EA play
