Age Of Empires 2 Internet Question

Well I copyed aoe2 to my hd and cracked it and then burnt it and when I go to play on the net I can't join any games. Why is this? Is there a way to fix this? and I also made a different copy of aoe2 and when I try that one it says insert the cd. Why is this? Is there a way to fix this? Someone please give me some feedback.
