Ok, I downloaded all the files I wanted, unzipped them, and they are currently sitting in downloads folder in the ZT 2 folder.
I read both sets of instructions, and from what they said, I should be done. And I think I am. I open ZT 2, and everything I downloaded shows up in the download section (one of the buttons on the start menu). Unfortunately, when I go to play a freeform game, none of the animals show up on the list, nor do any of the ambients appear.
Am I doing something wrong? Do I have my files in the wrong place?
