Can't get connection

[elray]

I'm running a wireless network and I installed Deluge today but I can't get a green light when I test the connections and of course nothing downloads. I also installed it on another computer in my network for testing..... that one connects perfectly Now both computers are running Win 7 both through the same wireless router. One connects the other doesn't. Disable the firewall and anti virus (Avast) still nothing, I clicked on the help button and it connects with the online help without a problem .... it just won't connect to download I have reinstalled it, still nothing ... what have I missed any help gratefully accepted.
