I understand you have re-installed feral heart over and over, did you not install Direct X?
You need that for the game to work. Also, you can always contact am admin or mod
and ask, they are pretty much experts
My advice to you is that its probly your Computer, not
Feral Heart's fualt. You should save important stuff like school work or letters ect. on a flash drive.
Wipe out your entire computer with a certain disk you can by at the store, and have a
fresh start with your laptop. First thing you might want to do is download feral heart, then Im sure i would work. This is not the only option, although this is what to do if your computer is derping way too much.
If its too hard for you, maybe take a break for a while?
