Ok download azeurus

http://azureus.sourceforge.net/ <-- Client

thats the client. If you already dont have Java installed, install that.

http://azureus.sourceforge.net/download.php <--- Java

now that its all updated and everything, you can now go look for torrents. The only thing with this is that you have to forward the ports that azeurus uses. 6881-6889 (if you are behind a router) if you are behind a firewall, configure it acordingly.
