This is what pops up when I attempt to log in.
It looks like you have a older version of FeralHeart, if I'm not mistaken. The update log is of the old download, and doesn't have anything current. Not to mention you have the old Watermill map on the load screen, as well as old interface textures (not unless you've replaced everything like I have). You'll have to download the updated version of FeralHeart, and it should work.
