If your updater does not work(like mine) just make a new folder called whatever, i pick update for lava, and download the full version, of MCDzienny, and extract it to update for lava(or what you picked) and from the full version, take MCDzienny Lava, MCDzienny_.dll, and the ChangeLog. After performing that, your server is updated and make sure to didn't replace and folders or the textdata.txt.
Hope this helped some people
