Re: AE CSS Crashed on exportwith Vista

you don't render clips in the render queue, you render comps. Drag the clip or other elements you want to use to the new comp icon in the project window, then instead of export, hit CTRL M to "make movie" which adds the comp to the render queue.

then you can render stuff out.

you might want to go to http://www.videocopilot.net/basic/ and go through the basic training tutorials. This should get you familiar with the interface and conventions of After Effects.
