Judicat0r: There isn't a way I can do it for you but if you just follow the instructions you are going to be just fine. ;)
Open the compressed file, then drag or copy the thumbnails folder in your Dungeon Keeper 2\Data\editor\maps\ or copy the content of the archive's thumbnail folder in Dungeon Keeper 2\Data\editor\maps\thumbnails.
Copy the remaining files in the archive in Dungeon Keeper 2\Data\editor\maps\ sand you should be good.
Start DK2 then select Skirmish, then change map and in the list on the right you should find the map, select it and click the check mark.
