Found a suitable archive.
As Thom said, this was a product released by Mjolnir and will not be re-released. The reason that it is no longer downloadable is that Mjolnir asked OneBookShelf to remove all the products that were formerly sold under their license when their license was terminated rather than transferring the sales records. However, you have paid for a product, so if you lose your downloaded copy, then PM me and I can send you that archive.
Best wishes,
Nicholas
