Don't know where you are finding your directions, but if you already downloaded a Knoppix version that you want by a torrent client, then you have the ISO file and are ready to burn. Don't "run btdownloadgui KNOPPIX-[date].torrent", whatever that means.

You can reach the wiki by the Documentation link near the top of this page. The Downloading FAQ in the wiki should give you all the info that you need about burning an ISO. Key points worth repeating are to burn it as an image, burn it at a slow burn speed such as 4x, and never ever select any option to make it bootable, but a quick read of the FAQ could save you wasted time and media. And if that run btdownloadgui KNOPPIX-[date].torrent instruction did come from the FAQ, then it is worth noting that the FAQ is user contributed and edited, you could edit it to clear up any confusion.

You may also want to do a quick md5 test on the ISO file before burning, although it is generally only needed with mirror downloads, as torrent downloads do their own error testing and correction.
