Cracking is illegal just so you know, but if you're looking for a crack since you own a copy and don't want to use the dvd each time, right? ;) then go to astalavista . com for a search engine with a drop down next to it to switch different websites to search for cracks on. Make sure you get a good antivirus before applying a crack (like NOD32) and never click on any extra exe files that come with. For Mac version, just find the download, it needs no crack. Download through torrents. Encrypt packet headers, and require others linking to you to do the same. Encrypt all traffic for better protection. Settings should be in the torrent downloading program, usually under advanced security.
