No. Firstly, you need to get the original Cradle package (2 files, zipped in cradle.zip) from
http://www.illwinter.com/dom2/maps.html and unpack it into the
maps subfolder in your dom2 folder. Rename the .tga file to cradlez14.tga. Then replace the .map file with the Version you got from Zen's site, and rename it to cradlez14.map
Get back to me if you still can't make it work.
