Please avoid using the following torrent clients here as there are incompatabilities when being used.

Deluge: all versions
Utorrent: 3x

We also recommend avoiding Beta versions of any client too.

UPDATE

Both are reporting incorrect stats to the site, and also utorrent 3x is causing problems for creating new torrents.
If you wish to use them and get a warning or worse banned for "dodgy" stats, you wont get account back as we asked you to avoid them
