Torrent already exists

I’m trying to download a few torrents using My Book World (white light), when trying to upload a couple of torrents the following has happened:

the upload page timed out, then when I try to uplaod the torrent again I get a message that the torrent already exists.  The drive became unresponsive so I rebooted the drive.  I cant find any files with even similar names to the torrents to upload.

So now I’m stuck, any ideas?

I had the same problem last night. Somehow someone else was connected to my IP Address. The telecom operator told me to not only turn off my computer, but everything else (especially my modem, as this will reset my IP Address), for at least ten seconds. It worked for me.
