Fluids Cycle Emission doesn't work?

  • Ex: I set Cycle Interval to 30, but at frame 60, 90, 120, the animation is not cycle. I don't know why.
  • I have never made the Fluids Cycle Emission works,
  • Here is my scene: http://vlc.t35.com/ The file FluidCycle.zip, maybe you need to wait to download file because of the free hosting.
  • Thanks for any helps.
