If you have a magnet link that hangs uT under any circumstance, uT might already have saved a torrent from the magnet (in its torrent folder) that can be used instead of the magnet. The magnet hang seems to generally occur after a torrent file has been generated. In my case i had six torrent files for it in uT's torrent dir with the file names file.torrent and file.#.torrent with # being 1-5. Meaning that uT had generated the torrent and then hanged, six times. In case uT hasn't generated a torrent, magnet2torrent.me seems to be a legitimate site to generate a torrent from a magnet.
