error message - no internet connection (i do) or there is a firewall blocking LW - ?

i have the latest version of basic limewire, but i cant download. i use windows vista. the error message says that i either do not have an internet connection(which i do) or there is a firewall blocking the program. In the lower left hand corner of the limewire skin the internet connection bars , only one is green, and there is a picture of a world with a brick wall infront of it. i have turned off all firewalls that didnt work and i also allowed this program to be able to get thru the firewall that has not worked either. i unistalled and reinstalled the program and nothing has changed. any suggestions.. im kind of at a loss.. i also am not that computer literate so that is why i am not quite able to put all the information that you are requesting... im not sure how to answer all those questions.... thanks
