So I got Nox installed and working, quest mode included, but I can't do LAN coop with my brother or sister. It tells us something about having a corrupted copy. I understand this is because these aren't technically licensed copies, but can anyone direct me to a workaround? I know I've done the LAN coop with them before, and know there was a guide for it somewhere, but I can't figure it out or find the information again.
