glitchy feral heart is glitchy

 So, I'm not sure if you know the game "Feral Heart" it's kind of like a role playing game. You can choose to be either a lion or a wolf and you can have wings and such, and join groups, but anyways, yesterday I tried moving my feral heart to my desk-top so that it would be easier to get to, but then it wouldn't open because it wanted me to download this thing.. but it wouldn't let me download it, so I tried downloading feral heart AGAIN and I logged on and I guess there was a new update, but there wasn't much, just music and new sounds. So anyways, I played on the map maker for a while, then I tried to go onto mutiplayer and this happened:

I tried going on a bunch more times, but the same thing kept happening so.. yea does anyone know how to fix this? i have a mac computer so feral heart has always been a little glitchy because it's made for windows not mac, but still, could someone please help me ;-;
