Downloaded and installed limewire but cant access it. Told port already in use...or I havent got an active internet connection (I HAVE) or firewall is blocking (CONFIGURED THIS AS PER INSTRUCTION) and finally that another programme has locked a file that was necessary for Limewire. I am new to this and my kids are getting mad at me!!! I can open the programme but it goes straight back to the desktop.What do i do.SusyBlue
