Hello! Installing this latest patch is very simple. First, you need to head over to the Downloads page: Link to Downloads page (https://feral-heart.com/download/)
Then you need to click on the second download:

Once you have that downloaded, you need to move that new file into your main FeralHeart folder. It will say that there is already a file like that in the folder and it will ask you if you want to replace it; when it does, click yes.
Once done, you should be able to connect to the server just fine =) You still need the Play Game tab to log in, however. So make sure you are logged into there and have the window up as you play. Link to Play Game page (https://feral-heart.com/login/)
