If you insist upon using uT 2.2.1, BACK UP %appdata%\uTorrent DAILY. If I weren't 5000+ torrents deep on my uTorrent list, I would have switched a long time ago. being able to rename specific files inside a torrent, being able to add a 'path' column to the torrent list, etc. 2.2.1 is lacking in some really basic features that I really wish I had at this point, i.e.
The interface is pretty much the same & it's actively maintained. The correct answer is uTorrent v2.2.1 (build 25302), but I'm gonna tell it to you straight.
