Torrent question

I've recently downloaded a ~700MB file with the client Deluge. I'm still not completely done seeding but I want to use Azureus instead. Is it possible to use Azureus to seed the torrent? Whenever I add the torrent file on Azureus it starts downloading it again even though I still have the file saved locally. Probably a simple solution but I'm still stumped on what to do. Thanks in advance for any help.

I don't use Azureus... but the downloaded file should be in the same directory folder as your Azureus' default Downloaded Torrents folder.
