I downloaded some torrent files that seem useful (nothing illegal, I assure you) but when I try to use bittorrent I can't seem to upload it.

I said open torrent file.
Selected the file I downloaded
I can see the name above the status bar
In the bar it says 0,0% done, ? remaining
then uploadratio and download speed both on 0

I can ask for information but that's it?

Anyone know what I'm doing wrong or what could be wrong?

PS I'm a complete torrent noob
