Installing Sims Nightlife w/o original Sims 2 disk????

[silbeej]

So i have The Sims 2 installed on my PC, and got the Nightlife expansion pack. I went to install it but i lost my original Sims 2 DVD, and it says i need it to install the expansion pack. Is there any way to get around this, for i have the Sims 2 installed, but can not find the disk. I don't want to have to go out and buy the Sims 2 again, just to install the expansion pack.

Thanks

If you've got your registration number for the original game, maybe you can call the publisher and see if it can help you out?
