This means that your MinimServer installation is broken in some way and double-clicking on the MinimServer application in the Applications folder has not started the MinimServer process.

There might be a message in the system console about this. You can view the system console by double-clicking Console in the Applications/Utilties folder shortly after you have double-clicked on the MinimServer application in the Applications folder.
