Hello. When I first bought this game I was asked zaregestrirovtsya and given the registration code. But when I reinstalled OS, I have downloaded Battlefield waist and waist inserts his data, I was asked to introduce the same registration code, and I entered. But I write this registration code is already in use. As a result, I can not enter into the multiplayer.

Hi @ImRamirezZiplo61

As I understand, when the game asks you to enter Product Code second time, it's invalid. It's a known issue and it can be solved via EA support:  How to contact EA support
