So what you'll want to do is download the Mediafire or Google Drive download from that post that I tagged before. I'd personally recommend the Google Drive link:

Once it is downloaded, double click on the folder that says FeralHeart it should look like this:

The open file should look like this:

You'll want to highlight the .exe (see above) and click "Extract To" and then find your main FeralHeart folder (should be C:\FeralHeart):

Next you'll get the following prompt. Just hit "Yes to All":

After that close out all files and start up the game while being logged in to the Play Game tab and it should work out for ya!
