Invite

Me and my friend was first trying to play proclubs but we didn´t see eachother in the changing room that you usually do and then we can´t go in to the league lobby. Only one of us is able to come in and when the other tries to go in it just says that an error has occured. And then he tried to invite me to his lobby in rush in ultimate team and it just said that the lobby no longer was avaliable. I don´t know what to do.
