Rubber, first don't :crazy2:
That looks like an error that I've seen with some versions of uTorrent. You don't say what you are using to create and post your torrent. Perhaps the staff here can help if it is QTM.
Otherwise my advice is to use a different program to create your torrent, an earlier version of uTorrent or something like maketorrent.
If you can give more information about exactly what you are doing it is easier too offer advice.
And the manual upload is not very difficult if you follow the instructions. 🙂
