Feral Heart

i havent played feral heart in years and when I saw it again I registered a new account, this one, since I didn't remember the password and its been inactive for so long its probably deactivated. I tried downloading the game but when I tried logging in it said 'download the latest patch', which I tried doing but the computer wouldn't let me do. and im trying to follow these instructions and others but i'm a little slow and I find it difficult to follow, I can't figure out how to fix it
