Book Rocket Mass Heaters

New to this Forum.. Interested in Rocket Mass Heaters.
I purchased the PDF  download of their book from Rocketstoves.com on credit card.
I was wondering if anyone else has had a problem? I cant seem to find where to download it.
Have not received an email or been directed to the download... Thank you for any help you may offer.

That's how I got my copy. I would have preferred a paper copy but I was too impatient. I should have waited as I enjoy paper so much more than pdf.

It was long enough ago, I don't remember how I got the download link. It's not in my inbox and I don't generally delete such things.

thank you.. still no reply.. the same problem with impatience.. im in australia so thought the download would be so much quicker..

alls well.. have finally downloaded the book..
