Newbilius writes : Important ! Downloading from mediafire you download not the disk image, but its contents , and as a result - lose audio tracks from the image. So if it doesn’t swing from the google disk (and there is already an excess of the number of downloads in 24 hours, it crashes with me) - then we are looking for the corresponding torrent and download it, for example, from here
UPD : New EBay Link
