Hi Sergey,
Are you sure? I use μTorrent (the 2.2.1 version) since years, and I know how to use and manage a torrent.
Whatever it is, this method don't works for me (at least), in fact, you will have no problem recovering the magnet link, but once you get it anything happens, it's going around and the seeds and the clients still unavailable because it didn't find any valid tracker.
However, when I log in all works propely, so how can you explain that?
Cheers.
