HI, I recently download avatar golf and everything works great except for when I try to run a local game. Everything works up to the point where you sign in people to play. The game crashes and says that an error has occurred, and it says to contact the creator and it says error code 4. Does anyone know what any of this means?

It is a bug that I am going to have fixed in an update.  For now just have all controllers signed in or turned off before you get to that screen.  You can read about it here in the Avatar Golf forum:

Thanks, It's a great game and I hope this will help me.
