I am having difficulty connecting with Limewire. Sorry I am so lame at this!

The connection indicator at the bottom right of the window says it is connecting (with one bar showing).
This stays like this all the time.
I have tried allowing windows firewall to allow this program to connect to the internet, but this has not helped.
I am connecting through the orange livebox, which does not have a hardware firewall.
Any helpfull suggestions greatly recieved.
