Well, Sixteen Tons Entertainment is not the only ones needing help. Why is it that, there's no clarification of how you actually get multiplayer to work, except for the same old discussions about ports. All those ports, are forwarded, everything. And I mean everything, even in my firewall. It's getting quite annoying, since I bought this game, not only for me to enjoy, but bought a copy for my friend! The reason I bought it for us both, was simply we wanted to play MULTIPLAYER WHICH IS NOT FUNCTIONING Oh, and I have a log here: [2015-07-28 18:00:36][QSF warning] QSF port forwarding manager: Failed enable NAT at external port "42007": "UnknownError"[2015-07-28 18:00:36][QSF info] EM5 multiplayer host: Connecting to the matchmaking server...[2015-07-28 18:00:36][QSF info] QSF client: Client [id: 0xffffffff] connecting to server 83.169.10.101 at port 42005Normally I'd be able to see the problem here, but I seriously don't. It can't enable NAT. Is that for real? My NAT is enabled, I even went through the hell to disable it, and enable it again, just to be SURE. The support has not yet answered me, the steam forums is dead, and even this forum is only populated by players posting on EM4, and occasionally coming to the EM5 section to pity on us, who bought this game.
