Calm down! Well you're sure you uninstalled FH? You need to try to uninstall... Well, I will explain you.
Open Start > Computer > Local Disk C: and then search for a folder called "FeralHeart". If it isn't on, go to folder "Program Files" and try to search there. Found it? Click in it, and go down. You will see 2 "unins", but click in the one that ISN'T is a unknown file/CD icon. Follow the steps, and it should be uninstalled. Hope this helps
