so you want to load the map (filename will be 1985) from the "creeper world 2 maps" folder?
if you search for "%appdata%\CreeperWorld\customgames\" on your hard-drive you'll be able to find the download folder for CW2 custom maps (probably located at this path, but it may be different on yours).
once you have done this i suggest you make a shortcut to it so you can find it easily in future.
i could explain the AC field path but the editor will be easier to understand than that.
hope that helps
