What I'm getting at is whether you moved the folder with the FLAC files after you made the torrent file. If you did, when the torrent file is opened, Bit Tornado would not recognize that you have the original FLAC files on your hard drive and would begin the d/l just as if you were a leecher.
If you did move the FLACs to a new directory, try opening the torrent file and when it ask for a directory to save to, navigate to the folder with the original FLACs and click OK.
