@Seakyusee1 This is usually the case when your torrent client is trying to download the torrent, rather than seed it. To fix this, remove the torrent from your uTorrent, then do the following:
Move the video file or the folder containing the multiple files into the folder that your uTorrent downloads into by default.
Download the .torrent file from the site to use
Open the .torrent file from the site with your uTorrent
As long as all the file(s) are in the correct place (ie the default download folder, or their collective folder within that folder), uTorrent should check the contents, then begin to seed it for you.
When it tries to download the contents, it is because it cannot find them in the default download folder, so it assumes you are trying to download, rather than seed.
