Ok, so you need to unzip you mapmods folder inside your Mods folder, and that should work. If the maps appear in game (in the scroll down list) then the manual editing part of the install should be OK.

Be careful your unzipping software deosn't extract content under a different folder (mine creates a new folder named after the .zip file, which has caused me to experience some issues in the past)
