[Disconnecting From Host During Loading]

Wait, how do I do that, but first off, what's a DE?

[Disconnecting From Host During Loading]

As you can see from the title, I keep getting disconnected from the host, or my friends keep getting disconnected from me during the loading screen. I haven't been able to play multiplayer ever since I downloaded it to my new computer, single player is fine, obviously, but I could use some help trying to figure out what's going on.
