      It seems that if every player in the network is not running the same version of Hamachi and Minecraft, things can break. Instead of trying to figure out which version is being used by the one who created the server, I would suggest that you guys all update both Hamachi and Minecraft to the latest version to avoid any back and forth or downgrading. Upgrading to the latest version will also patch known bugs and bring new features or functionality.
