LW unable to initialize and start
 

I have downloaded the basic version of Limewire, but when iclick on the icon to open it, a message pops up saying LW cannot initialize and start and that thi is often due to firewalls.
Limewire is on the execeptions list in windows firewall. I have tried using other forums for help and none work. I had LW on my old computer and had no problems.
I am now using XP, the internet is through a network at home, I have Java...I am at a loss.
If anyone has some insight, that would be much appreciated.
