Hi,
If you only download and never create or upload torrents it might not matter at all for you so you can probably ignore this post.But if you are uploading torrents please read this...
Due to many people having similar problems when creating and uploading torrents (not only here but all over the net) with utorrent versions 3.1 and up I recommend that you don't use these unless you only download stuff.
Typical problems with the created torrents are "not valid bencoding" when trying to add a torrent or seeds never starting.
The version that seems to "always work" is utorrent 2.2.1
You can get it from here
http://www.oldversion.com/windows/utorrent-2-2-1-25110To use simply run it instead of your current version. Create the torrent with it and make the upload again with the new torrent file.
MAC?
Mac Users: Use Transmission to create torrent if you have issues with upload
