Notice of Action under the Digital Millennium Copyright Act?

As far as I know, they won't take any more action unless they suspect you of downloading more content. The Notice of Action was just a warning that if you continue to download stuff they could take legal action. I believe that you should be safe for now. I would post this question on the utorrent forum though since those individuals probably know a lot more than I do about file sharing. They could also help you not get caught if you wish to download more lol. I would suggest laying low for a while though.
