This is an official notice that LimeWire is under a court-ordered injunction to stop distributing and supporting its file-sharing software. Downloading or sharing copyrighted content without authorization is illegal
My advice is to buy with your $$$ the software you want instead of stealing it.
yikes, i didn't realized they are in legal trouble. my friend ancient dragon is right, while file-sharing clients are not illegal, unauthorized copying and sharing or content is... that's not to say that i'm assuming you are downloading anything illegal. many big name vendors make their software, files and drivers available via torrents. uTorrent is pretty popular and reliable.
Obviously you are not suggesting, are you, that anyone did this to somehow get a free copy of a commercial/copyrighted music track otherwise you would be in breach of the 'keep it legal' rule: "Do not pursue any illegal activity within forum posts"
