Buddha,
Let me see if I can offer additional assistance. Here are some screen shots that may provide you some help in getting your terrain to work in Le Missioneur.
Screen #1 You can see I have Cyprus loaded in the Terrain folder with all of the necessary files.
Cyprus.ini
Cyprus_data.ini
Cyprus_dogfight.ini
Cyprus_movement.ini
Cyprus_nations.ini
Cyprus_targets.ini
Cyprus_Types.ini
Planningmaps 1,2 and 3.
Screen #2
If these are present you should be able to start Le Missioneur, select the terrauin and see Planningmap1.bmp
Screen #3
You speak about adding ships and ground objects, are these items loaded into your Terrain_Types.ini file? If they arent a part of the stock program they need to be loaded into the terrain_types.ini file. You can use notepad to open the ini file.
Lets say you want to add a tank, click the tank icon and you should get a dialog box that offers you ground vehicles.
Hope this helps
