I know about looking for the "my lord of the rings" in application data, but the problem is, I don't have a my lord of the rings folder in any folder, so I have no where to install my maps. I used EADM.

Press WindowsKey+R
Type in: %appdata%
and press enter. This will open a window called Application Data, which is a hidden folder. Your 'My Battle... Files" are found here.

For future use, maybe make a shortcut. Or when in the Application Data folder, right-click an empty space and click Properties and you can make the folder unhidden.

Thanks for the help, but the problem is it isn't in the Application Data folder or any other folder, and I've even used find/search and showed up with nothing.

For the record, it's

My Battle for Middle-earth ™ Files

not My Lord of the Rings Files.

And if you're using XP, the folder is definitely in Application Data. If you're using Vista, it's in a similar place which should still be findable using %appdata% as the address path.
