I installed ArmA2 and ArmA2:CO, downloaded all the files from the DayZ website (US mirror has been down for 24 hours or so, at the least) and extracted them into the correct Steam subfolder where Operation Arrowhead is located. I followed all the instructions I could find on the forums (the sticky on how to install as well as the YouTube video on the actual DayZ site). The game will load, show me arma2 and dayz on the menu screen but when I load a multiplayer server, it loads and loads and loads and then either returns me to the multiplayer server list or to the lobby. Sometimes it tells me it can't load because of some /congif file, weapons or sunglass usually. What's going on here? I've tried multiple times to download, redownload and replace the DayZ mod files as well as force updating using the DayZ update tool. Nothing works. Do I need to completely uninstall ArmA2 and then reinstall it?
