Help?

I need help. Okay, so I have the freelancer disk, and I just tried to run it (Already installed FL), but this box keeps popping up saying: Can’t locate CD-ROM, please enter correct CD-ROM and try again. Help please!

Also, I’m doing this on a laptop, but it won’t work on any of my other computers either…

I don’t know if this is in the right place to post this, but I couldn’t find any other places.
