Let me preface this by saying I followed the installation video, installed things while going along with the video, to ensure everything was done properly. Now, on to the problem. When I load up Arma, all of the mods load up fine, and show on the main screen as being there. Just to test it out, I went to multiplayer, and clicked on 2 or 3 different 506th servers, and all of them showed that I didn't have some of the required mods. Mods I DL'ed, and installed following the video. No error messages show up, or anything like that. Just shows a red light, instead of green next to the required mods.
