The game says I am free to evacuate (because the mission is completed) ...

But when I click the Evacuate button it doesn't do anything (it just gives a message about creating some kind of evacuation zone)

It is not helpful at all that NO manual is included with this download ... the "manual" shows ...

There are no instructions for the "Soundtrack v1" zip file.

It only contains MP3s in a folder called "base files."

Are these files/this folder supposed to be put in the game directory? and how?
