OK i have vista home and am the administrator. I think i know what the problem is but know know how to fix it. I made sure it was on my allowed list for my windows firewall and then it said that i had Norton running a firewall and not windows.and i dont know how to get to nortons firewall... its not even suppose to be running but i have had all the software on my computer and none of it has changed. not sure why now limewire wont work. I also completely uninstalled and reinstalled limewire. I also deleted all the limewire folders from my computer and reinstalled that way. I just want it to work. and some of the explanations make no sense... im not a computer engineer so make it easier to read please....
