"address book" needed!!!

i used to have the address book in my mac, but now, all of a sudden it got deleted (i think)......

i cant find it in the applications folder, I've also searched for it in spotlight and did not find it...

can anyone tell me from where I can download it?? or if there is a way to restore it somehow.

thanks

Are you using Time Machine or another back-up utility ? If not then getting your data back may not be possible but you should find the app on your istall dvd's that came with your machine

Hope this helps
