Help I screwed up

Ok I did it, don't know what or how,
, but the cfg file and the model file are gone from ny cessna 172 folder and when I go to fly I have a gray ac. 10 lases for me 
I've looked on the install cd disk 1 and could not find a file for the c172.
Can anyone help me find it on the disks so hopefully I can replace it in my program without having to do a complete reinstall.
Thanks Steve
