If you're willing to try,please follow this:
- download http://filebin.springlobby.info/springl ... -win32.zip
- open your the directory where spring is installed in explorer ( default is something like c:\Program Files\spring )
- make a backup copy of springlobby.exe (select it, ctrl+c , ctr+v )
- close springlobby if it's running
- extract everything from the archive into the spring install directory, replacing any existing files
- run springlobby again
- start update
- follow on screen instructions
Please report back both in case of success and failure, including which windows you're running, the path (directory) where SpringLobby is installed and in case of Windows Vista/7 if UAC is on. If an error occurs please note the exact message (screenshot would be fine). If the updater itself fails there should be an updater.log in the install directory that you could attach.
