LAN CTD

[FlyingR]

Hey guys,
So I just gave my mate PR, he installed it, and we tried to play a co-op LAN game via an Ethernet cable connecting our two computers. I created a server and got going. He found the server and joined, but when the loading finished, his PR just closed down. We tried again vice versa, and the same thing happened to me. We then tried using a wireless hotspot on my computer, to no avail. Before I go creating a profile on the PR forum to troubleshoot this, does anyone have any idea what the problemo is, or what I'm doing wrong?
