Hi, I'm new to ARMA and DayZ and I'm having difficulty joining a game of DayZ, I have installed: ARMA 2, British Armed Forces, Operation Arrowhead, Private Military Company and the DayZ mod... whenever I try to join a game, I always get kicked from it before it even loads, stating that I have modified files in the Operation Arrowhead main folder. I uninstalled OA and tried to relaunch DayZ but it wouldn't work without it, so I'm currently reinstalling it. Is there something completely obvious I've missed, or is there a lot more to all this than I think there is? if someone could please let me know that would be great as I'm really looking forward to playing it as soon as possible! thank you in advance, from Lewis
