When utorrent reopened, all downloading torrents disappeared

[Techsfox]

Hi and thank in advance for your time

I am a great fan of utorrent and I have used it so much that I have about 700 completed torrents and other 300 ongoing torrents in download queue, the problem is that one time when I reopened utorrent by opening a torrent file it opened with all torrent lists white clean expect the new one torrent! I have lost all the ongoing torrents download processes and I have lost the list of completed torrents which I like to use for exploring the downloaded files.

Thank you again
