Ok, so I go and try to host a server which I have been able to do before the new feature for making it so you don't have to port forward came out, and my ping is always dead when I use the In-game server switch mod to check it and no one comes on. Usually when I check for the ping, it has a ping. I updated my IP Address today and updated the port forwarding with the new IP. And it still didn't work. Why won't it work?
Off-topic: Also, I download a music file from the forums to put in the add-ons folder and it won't work, why?
