I can't find such an option to change the download rate, and it randomly just stops downloading. I had to force it to download the next part after it had apparently been stuck for a good while. I'm sorry but I just simply cannot see the appeal in this program. It's been very buggy all day long and very confusing to operation. This is why I'm so desperate for a torrent of it, but I can't find any dependable websites or torrents that aren't bogus.

Update: Well I just managed to find the option to change the speed and now it's going at a much more reasonable 120 KB/s. I still find the program difficult to use though as it doesn't like to automatically advance to the next file.
