we can't know. We don't know what settings you used in E3D. It simply seems you completely misunderstand how the noise functions in the plug-in work and auto-animate and thus you cranked up a wrong value.
In E3D I used the rocks with the following settings, in fact I did not change anything just applied the Icy material to the rock as Saturn rings are iced.
As for the comp generating the rings, you can find it here
I've just changed the map to create the planet itself.
You might need to adjust your antialiasing and super sampling...a lot.
probably a silly question, but where should I find the adjustment parameters????
I don't have Element v2 yet, so I can't show you a screenshot. Just dig through the options in the Effects panel.
