How to reinstall the game without purchase again?

Hi @y_hanna123H,

You don't need to buy the game again after reinstalling the EA app. If you cannot see the game in your account anymore, it's very likely that you have logged in to a different EA account. To get assistance with your account, please contact EA Help Support as they should be able to help you with that. 

Let us know if you need anything else,

@EA_cuervo Weird that I don't see it, for example FV24 I can see it just need to download it.
Can you check if we can recover account library?
I really appreciate your help, I don't want to buy it again, just bought it 3 days ago.
If you have a support team which I can contact 24/7 it will be helpful too.

Thanks in advance!

I can't assist you with account-related issues here at AHQ, but our support team can. Click on the link to contact EA Help Support.

I hope this helps!
