Can someone help me with installing Logic Studio 9?

I just downloaded a torrent for Logic Studio 9 on my Macbook. I got a serial number for the installation and it worked, but then it asked me to insert a disc for Audio Packet 1 or something like that. This guy on Pirate Bay said that you can still run Logic even though it says that installation was unable to be completed. There's a thing on my desktop titled "The Numbers Game.logic." It asked me for another serial number and all of the one's I tried from the website that people were posting didn't work. Please help me.
