Feral Heart

OK......I downloaded the newest FH patch and i double clicked on it, but it keeps showing a folder with "Feral Heart" under it. I click it, and it shows all these things like settings, and maps, and other game things. I click on one of the grey ones, not a folder and it shows a download for it. Should I download them all, or which ones should I download? I'm very confused because every time i try to log into FH it said, "Please download newest patch from www.feral-heart.com. " So i come here, and download it but now im stuck trying to figure out what to do. THANKS!
