By manual update do you mean not using SixUpdater? I just completely uninstalled and reinstalled Arma II along with dayz, but cannot even get past "waiting for server response" which seems a problem for many people now.
109 views and no responses? There's another thread where someone has a similar issue with dayz saying they have an even older version. Bump for a solution
This is happening to me as well. Tried Six Updater as well and used multiple 1.5.2 servers to update. Still says I'm on 1.5.1 Also deleted all my dayz files and redownloaded and unzipped them into the folder and update from Six Updater after. Still nothing.
