Uninstall, go to "my computer" Local Disc C (or whatever you put the game in) and delete the entire game folder, and make sure you delete everything, like the game was never installed, then go here:
http://dbo.wasabii.com.tw/download/D...26.exe.torrent
if you dont have a torrent, then go here:
http://dldbo.wasabii.com.tw/DBO_Downloader_20121126.exe
.
When it's done, install the game. When it's installed, Start the game WITHOUT ADMIN, the launcher will do the download 2 times. When it's over, close the launcher, right click the Shortcut (in the desktop, with wierd characters) click properties, and then on the bottom click "Advanced", click on the first option. Apply everything and open the laucher normaly, AND IT'S DONE!
