Zoo tycoon 2 game installed on my computer and you lost the CD can you still play it?

Sorry, but the CD must be in your computer for you to play the game. It stinks, but that's the way it works. If you cannot find your CD, you can download demos of the game onto your computer from the Zoo Tycoon Official Website, but you cannot save your zoos and the animals and design possibilities are extremely limited. Just type in www.zootycoon.com (not real address) into your computer and it will automatically take you to the website, or it will be first in the search results.
