Thanks for the comment, from your screencap it looks to me like there's no sound coming from the input you've selected. Most of the visualisers will be blank unless there's sound being played through them.
Have you enabled your sound card's playthrough device? It will be in the recording devices (you may need to right click and choose "Show disabled devices" to see it), and if you've got a realtek sound card it'll be called "Stereo Mix".
With some music playing, try going through the list of input devices in visualistar and see what happens?
