same thing has been happening for me, i havent been able to get Feralheart started at all. I tried Uninstalling and reinstalling, creating a new character, deleting and re downloading, and nothing works, i log in and pick a character and it wont work at all. Same message is "Feralheart.exe is not working", so far its been 3 days since ive been on. I hope they figure out the problem soon.
