All you should have to do is drag it into FeralHeart > Exports in the main FH folder. If it is saying that it is damaged, make sure that your computer is downloading properly. I'm confused as to when it's telling you that it is damaged. When you go to download it? After it's been downloaded already? Or are you trying to open the file? fhm cannot be opened. Well, they can, but you don't want to be messing with that xD Just drag it on into exports and it should work. Should.
