hi there, first time on, i'm a total computer idiot so i really struggle with talk about ports and tcps and ucps

anyhow i think i have service pack 2, i'm not sure if thats the blue or green bar

recently had some work done to my computer and i cant get back on limewire

i went to the firewall / exceptions / add programme

then i got limewire on the list and clicked it, still doesnt work

to be honest, some of the stuff i'm reading here i dont really understand, i think i need some idiot-proof instructions, sorry
