Smoke and flame not showing up in render view mode and in render I started making a volcano simulation recently and suddenly, today when i finished rendering my sample animation I noticed that the smoke and fire of the volcano are not present, i went into the file and rebaked the smoke and fire then I went into the render view mode and I didn't see any smoke or fire there either! I should note here that in object view I saw all of the smoke how it should be.
Pleas help me, this is for a school project and i have to hand it in soon.
Here is a link to the .blend file and an image of the final 
render:

Your smoke bake has to be starting inside the start/end frames. If the sim start frame is before the timeline start, the sim won't start at all.
