Disco Boy, if you would please mind to tell us exactly what you did and what is not working, we might be able to help you.
Did you extract the whole zip?
Did you use the setup.exe?
Was the installation successful?
Then check if inside your JA installation directory there is a
dark directory,
and if this
dark directory contains a large PK3 and different small files.
Do you have a desktop icon for the DFMOD?
What happens if you double klick it?
Please write me its properties in a PM if you like.
If you don't give us "proper" error or behavior description, we cannot solve the problem
