Hey Spora,
It sounds like you followed the correct procedure. Just curious, what makes you think it is wrong? All flat, all water?
A couple things to check first.
1. When you go into the AHeditor it sometimes makes you think you are looking at the entire terrain. You are really only looking at a small part, the terrain is actually very large. It should take you about a minute at full speed in editor-eye to reach the end of the map (whole world goes blank when your run too far). When you enter the AHeditor you will be in the centre of the map you created with MapMaker.
2. Look in your AHeditor folder for a file called "terr.bmp". This file is created by the AHeditor each time you enter the program. It gives you a picture of the terrain it just loaded. Does the terr.bmp look like the area you created with MapMaker? (it can look a little dark, but do the major features look like they are there?)
3. When you created you terrain in MapMaker do you get correct maps in relief, cover, and elevation? (just checking to see if the elevation file loaded correctly)
4. Under aheditor/settings look for a file called "curter.cfg". It contains the name of the directory it is loading terrain from. Make sure it says lappi.
Regarding your map, you have to create one yourself. If you search through this forum, someone wrote a very nice discription on how to make the clipboard map.
Hope something in here helps. If not, give me the lat/long/range you are using and I'll test for a problem.
