You can try to install a general
P2p software like
Imesh or
Limewire.
If they work, then i guess the proxy is a bit leniant.
However, if it still doesnt work,
try changing its connection
port by going to the
Preferences.
To see some of the ports that are open on your system, you may type
netsat-a at the dos command prompt.
Accordingly, set the port value to that which is open on your system.
Bittorrent failure may be due to several other reasons, try the same thing above in bittorrent as well..
