Trying to make a Map

[jumper0815-PG-]

Like TheCorN, I tried to build a map with the Tutorial from Bubba.
I directly failed at the moment when it comes to select a terrain.
I opened the MED and could not find a terrain to select. Maybe the only prob I have is, that my English is not the best to find the right entry in the menu.
Also i searched my whole folders from the DFX-Games (regular, Mod 1.2 and Mod 1.3) but did not find anything that looks like a terrain file.
Is it possible, that someone send me a blank terrain file by mail so that I know what to look for and search my folders again?
Thanks for the incoming help!!

There is a program that Hunter has made that will show you terrains before you pick them to see what they look like.I am a newbie map maker but will help anyone I can.Thanks TAR
