as previously stated we only run ONE server that doesn?t require any mods, that server is the INSURGENCY server, i asked what you used to load up DayZ, because some launchers leave the launch parameters after you uninstall them, so i?m guessing that your game is still loading up your DayZ key. If that is the case, you just need to clear your launch parameters, for steam, right click ARMA and go to properties, then set launch parameters and see if it?s loading up a DayZ key.
