I have a problem with UTorrent, I can download perfectly files and they are saved in my computer. However, when I turn off the computer and then turn it on my list of completed torrents disappears. I mean the files (videos) are in my computer and I can play them but UTorrent list is empty. Because of that, I'm not seeding and therefore I'm not receiving bonus points.

Has happened something similar to somebody? How can I fix it?

Thanks in advance,
