I saw the Game Warden post, but I didn't do all of it (creating a polit, etc) because I figured I didn't need to worry about that if all I wanted to do was play some LAN, but I'm gonna give it a try now. I'll let you know.
I've been playing the retail version with my roomie, but it just dosen't have the same, oh I dunno.. gorgeousness and gorgeousity? of SCP.
Hopefullt this works.
Well, It looks like this fixed the problem! I'm able to get to the mission select screen now. I'm curious as to why connection to FS2NetD is neccesary, for LAN play, although this isn't a problem for me. is the connection to the network somehow validating the missions? ANyway, thanks for the suggestion.
