Hi.
I just installed the mod with the same download that is linked in the first post, and it works fine.
Are you sure you are installing it correctly?
Just drop the folders in the .zip in to the game directory, and replace all files (30, i think), and you should be good.
Or you could just uses JSGME if you have it set up.
It's installed the same way on both version of DCS.
Not sure what else the problems you are having is caused by.
Hope that helps.
