You shuld try the new login page, found here:
http://feral-heart.com/login/index.php (If it works lol)
Sign in regularly there, wait 20-30 seconds, then open FH (Don't close the tab, or minimize it. Keep it behind your FH) and have fun playing!
Note: The page may or may not log you out every few seconds. If this happens though, then try a website refresher. Other floofs can tell you more of what to do with this, but yeah.
Hope I helped you!
