cod4 mod tools dont work

[3dsplorer]

Hey, I've been trying to get the cod4 mod tools installed, but they dont work. Like the readme said, i copied the contents of the .zip file to my cod4 installation folder. It didnt work. the map editor, and other tools wont launch. And btw, is that really the old q3 radiant they are using ??? wow didnt know the year was 1999.
