To be honest I'm not sure it IS the FeralHeart server causing this problem, since I've been online almost everyday for awhile and I haven't experienced any server problem.
If it would be the server we would all get affected.
Have you checked your AntiVirus/firewall protection and made sure it isnt blocking FeralHeart? It's not unusual that virus programs do that when it doesn't recognize the game/program being run.
How about your computer? Is it up to date with graphic cards and such things?
Please check out this link if you haven't already: The BIG help thread (http://feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=10423.msg144690#msg144690)
There might be something there that could help you.
Good luck!
