That happens to me when I installed the game, I think I know how to fix it, you could either open feralheart in its folder (I think you did that already) Or you can set it as administrator, It might help, notify me if it works or not.
How about downloading this? http://www45.zippyshare.com/v/94444407/file.html (http://www45.zippyshare.com/v/94444407/file.html)
after downloading, place it in feralheart folder.
