Alright, I figured out what to do on my own. It seems it really was because of the Apex expansion. I had an old version of Arma 3 which didn't have a lot of objects, which were later added by Bohemia Interactive through various updates and also Apex I guess. So if you get these error messages, it is most likely because of this.

Hello, I'm very new to this so I don't know if I'm missing something, but whenever I try to host the crCTI I get an error message "npmissions\__cur_mp.Stratis\mission.sqm/Mission/Groups/Item47Vehicles/Item0.vehicle: Vehicle class HeadlessClient_F no longer exists", I can then close this message and set everything up. But when I start the game, another error message comes up saying: "You are missing structure classes which are required by this server: Fridge_01_closed_F" and when I close this one also, the Mission Accomplished shows up and that's it... What does it mean? Do I have to download something? Or is it because I don't have the Apex expansion? I really don't know... can anybody help me? :)
