My game won't load do to DisplayName field missing form registration

So i tried loading my game for the first time and all it does all the time is just closing EA app and opening widnow which says ´´DisplayName field missing form registration´´ which wants me to register into it with my EA account. When i do that, it just closes and reopens EA app and nothing happens. If i try to hit play again, EA app just closes and reopens instantly without showing the previous window. So my EA app just keeps relaunching when i hit play and thats all.
