Just getting into bittorrent myself. Tony, not sure exactly what error you are getting but if you are trying to DL the 'torrent' file and bittorrent automatically fires up but come up with an error... either try cleaning up all your explorer temp files or save the 'torrent' file to your HD (do a 'save as') and then double click on the torrent file on your HD. BT should fire up without the file path error.
Some bug I read about with BT and how temp files work stopping it from running automatically.
