You will have to delete the entire thing and download it not from torrent. The torrents pretty glitchy, but that should work.
If not, try deleting all the files and reinstalling FH? Perhaps the files were corrupted in the download.
Er, FH torrents always worked fine for me, at least. Downloaded & installed it once again to check and everything's fine. Unless it's your internet, in which case I can't help... but no glitches encountered so far.
Feralheart still doesn't seem to work. As far as I know, it should be compatible with Windows 8 as well. I don't have an Antivirus on this computer I think.
Torrent's being a massive nerd as well, and I can't seem to get it to work no matter what.
Get an antivirus.
NOW. How did you forget to install your antivirus? You should be shameful for not already having an antivirus! /jk But seriously, get an antivirus. I would recommend Avira or Kaspersky.
Anyways, did you update to Windows 8.1? In my Windows 8 it worked pretty fine. In 8.1 I'm not sure as I need Hamachi and 8.1 is incompatible with LogMeIn applications. idk
