So are you saying that you manged to change the port or do you mean that when you hit CTRL+G nothing happened and if so then make sure that Utorrent is the active window application by clicking anywhere on Utorrent before hitting CTRL+G and then do the command an it should bring up the speed guide window.
If you changed the port and you are still getting a blacklisted message from that site then I would suggest you go post in there forums and ask what range of ports they allow to be used on there site and use one of those.
