1) Norton Security is probably blocking you from getting to the site (for what it's worth, I'd replace Norton with something else - it's notoriously system-hungry, and there's much better alternatives around - the new AVG Antivirus+anti-spyware for instance, or NOD 32 + Spybot Search and Destroy/CCleaner/Adaware)
2) Limewire isn't the best type of program for doing peer-to-peer downloading (although the ability to preview what you've downloaded is useful)- you might like to try one of the various "Bit-torrent" programs like Azureus or Utorrent.
I know these aren't the answers you might have wanted, but they would make sense if you're wanting to download software from something like Limewire
