okay, i messed around and made a small game. then i clicked host, and set its port. but when i
open another instance and try to connect to it, I get this errors:

Your key has expired. To renew it, you must try again while connected to the Internet.

why does it do that? i made several new keys and it won't let me connect to my own game
once its hosted. -ponder- very hard to bug test without being able to login as another player.
