I've made a map using the dftfdmedv193a. I chose the s1.trn. How come noone else can get into the map? When they try, they get the "no height map" error message. A friend of mine has the same editor but he says he doesn't have that terrain listed. Any clues??? How did I end up with a terrain that noone else has? I am dumbfounded, stupified, and completely frustrated. PLEASE HELP!!!
