Adding onto what was said before me, if the "Skip" button on the Adfly page isn't working properly, you could try downloading the game through another internet browser. If you're using Chrome, for example, try using Firefox. If you have removed the Feral Heart game, itself, but still have some of the files, you can delete these by right-clicking on the files and selecting "delete." Be that the entire FH folder and installation is removed before trying to download again.
