Before the I Dl'ed the SW MKV I had never really used torrents either.
I DL'ed BitTorrent and absolutely nothing I did could get it to work... opening ports, messing with the firewall, nothing. It just wouldn't "start." I DL'ed uTorrent and it worked immediately, which is bizarre because I guess they're made by the same people and are nearly the same. Anyway, it's worth a try.
