If you get "DisplayName Field Missing From Registry" error

[cogocahe]

If you get "DisplayName Field Missing From Registry" got to "https://activate.ea.com/", register or log in with an existing origin account and enter your serial there. You can also do this in the origin client itself.The game will appear in your origin account and will be playable over steam too. I don't remember if you have to insert the authetication code again if you want to play it over steam, but it works for me now, although I had the error. If it nevertheless won't work the game should be in your Origin account and you will be able to play it there.

Hope this helps
