Feral Heart

When i launch the game and i type in my Username & Password it comes up with a blank box and after a few seconds it puts me back to the starting page. I have also tried putting my email instead of username but the same thing happens. Am i putting it in the wrong box or am i doing something that i am not meant to be doing? I am a new player so i have no idea. Heres some screenshots: https://imgur.com/a/Rw0MK
Also could it be because it is not compatible with my system? Im using Windows XP.
