bittorrent is a file-transfer protocol.
it's a download software which can download stuff from other seeders
anyway, i think you should make sure u can get online first. then worry about bittorrent.
in case u can go online, but just not downloading anything using bittorrent.
one reason might be your file doesn't have a avaible seeder or source online.
second one would be some bittorrent port was blocked if u have a router between your comp. and the internet.
hope that helps, you could get more information about bittorrent at
