I understand that you must've heard this a bunch of times, but I haven't been able to battle. I can't host any battles; a message pops up reading "Failed to listen on port. Please load game and try again."
When I attempt to join, it gives me an IP code (which I assume is my own) and, after attempting, it says they cannot connect to the host.
The second situation is more understandable, I obviously can't connect to myself as a host if I can't boot up the fight as a host. But, I really don't know how to deal with the first matter. If anyone else that has the game can help me out or if you could give me a help, Twilight, I'd be very thankful. I'm a digimon nerd and would love to play the game at least once more.
