ScreenSaver Help!

[ShamrockGamer]

I am trying to set lively as my screensaver and I got a video set and the one time set up plugin (Although it keeps failing and I have to set it up again) and I have lively set for screen saver, but when I wait or tell it to preview the screensaver, nothing happens the screen flickers very briefly and then nothing happens, any help would be appreciated!
