PAI damaged Terrain cfg file?

[Wing Nut]

Interesting thing.  While installing aircraft from PAI last night, I fire up FS and got the message 'The Terrain.cfg is missing or damaged.  Some Terrain features may not work.  Please reinstall FS9 to repair the problem.'  Anyone else ever run into this?

You could try getting the file from the disk and replacing it, but i'm not sure if the sim has added anything from whatever addon scenery you might have. I looked through mine and couldn't see anything pertaining to my addon scenerys. If that don't work, then a reinstall might be in order. Don't know why PAI aircraft would affect files like that one.
