just a small problem

[funny-head]

when i do a search for an audio or anything it say's "limewire is currently to the network, your search may not include many rusults untill you are fully connected" i am not sure if that comes up everytime or something.

also my connection bar remains at 1 bar all the time and near it i have got a globe with a wall infront of it, i think thats the problem but i got vista and i cant acces my norton setting to allow it through a port,

please help me thanks
