Aye, ye' have put this in the right place, floof.
Chances are yer anti-virus/protection system is labellin' the files as corrupt thus is the cause of yer inability to download the setup files. Try lowerin' yer fire walls (temporarily) till the files have been downloaded then raise them again. I assure ye' that FeralHeart has absolutely no viruses attached to its components. All is safe so long as ye' download it from this site only.
If that doesn't work, try gainin' access to the program uTorrent then downloadin' the Torrent download. Ye'll need uTorrent in order the access the torrent files though.
