Terrain.cfg missing or damaged

[draconous]

Well I appear to have messed things up, I get a error message saying that my terrain.cfg file is missing or damaged. I was installing Cloud9 Aviano Scenery. When I first loaded FS it said that my Scenery.cfg file was missing or damaged and closed but I was able to restore it but I cannot find my terrain.cfg file to restore or replace (not that I have been able to find a replacement) can someone please help me :-/
