Limewire No Longer Functioning (mini mac)

[Dancemaster]

I have searched the forum, but the solutions offered to my problem are not working. Like others, I cannot get the connection bars in the bottom left corner to turn green. I have been using Limewire for years, but basically it recently just stop working, though I have not changed any aspect of my software or hardware. First, I downloaded the latest version, no change. I removed all traces of Limewire from my HD and downloaded the beta version, no change. I played around with the firewall on my mac, but no change. Besides, I have never ever had the firewall activated anyway. Now I have set the firewall up as instructed just in case, but no change. Basically, Limewire has suddenly become utterly unusable to me. Any suggestions would be appreciated. I have a mini-mac with Tiger.
