Check whether there is a typing mismatch. The name of the terrain folder (which you call Iraq03 or Libya) has to mach EXACTLY the names for the INI files inside the folder. Iraq03 and Libya are not the correct names.
So if it is Menrva's recent Libya Central Mediterranean terrain you are having trouble with, the terrain folder MUST be named LibyaCM, because that is the name of all the INI files in the folder. If you have a mismatch, like just naming the folder Libya, the terrain won't show up.
Likewise with the two recent Iraq terrains. The folder must be named IraqWA or IraqWA_03, depending on which version you have downloaded and are trying to use. If they are not, they won't show up.
