Is there some special way to host this on a server on just vanilla Arma 2 without having to go through combined ops? I get a error saying "unable to play/edit etc" (something to do with deleted files and such) when I try to host on just Arma 2. However when I host on combined ops/OA it works fine. Im curious how people are hosting on vanilla Arma 2 since the multiplayer lists/servers are separate between Arma 2 and CO/OA (at least for me). More people play it on the vanilla side it seems which is the reason for asking this. I thought that was the whole point of CO was combining Arma 2+ OA into one game. Its been a while since I last played Arma and not quite in the loop with the expansions and such.
