why do i get thrown out of the party whenever i try to play with a friend?

Hello there, I just downloaded the game EA Sports PGA Tour and I wanted to play with my friend. Everything works, except whenever we try to start a game, after the loading screen appears and I wait for a while, I get thrown out of the lobby and I'm back on the main screen. For my friend, the screen just goes black and after a while he's also sent back to the main screen. I'm not sure if I'm the problem or if my friend is, but I really want to play with him and we've been looking for ages and haven't found a single reason or solution for this problem.
