HELP! Black render with fire and smoke!

I Downloaded the latest Blender 2.71 Release Candidate 2, set it to CPU render in Cycles and I want to render fire and smoke.

I followed this tutorial throughly:

But when I hit render, it gives me no result. It works fine in 3D viewport, but not in preview or final render.

What am I doing wrong?

As I said, its all set to CPU, not GPU.

What am I doing wrong?
Are you not going to supply screenshots and blend files to help out anyone who wishes to take some of their precious time to help you ?

same problem here :confused:

Sorry, I completely forgot this thread.

It works now that I have installed another build.
