My games on origin have disappeared. suddenly I log in and my entire battlefield 3 is gone with all the expansions. how can I retrieve my games back?
1st Make sure you are logged into the account on which the game/s were registered.
If you're getting the "code already used" message, it means the game code has been registered.
Please make sure you have "Show: All Games" in MY GAMES selected. Have also a look at "Hidden Games" because manually hidden games will not appear in the "All Games" view.
Should you have issues with a recently bought game that is not showing up in your games list in Origin, then please take a look at this post first: http://answers.ea.com/t5/Origin/I-bought-a-game-but-it-does-not-show-up-in-Origin/m-p/54908#M951
Your game should show up in the "My Games" folder of the Origin account you used to enter the code. If your game isn't there, you're either logged into the wrong account or the game hasn't been activated yet. It can take a while. If it doesn't show up you'll need to contact a Game Advisor.
