Did you remove everything from C:\FeralHeart before you reinstalled?
Have you also tried running the game as administrator if possible?
If you did those two, what about opening the ogre.cfg inside the game folder and set it to another rendering mode there. Just open the file with notepad then change the top row from OpenGL to Direct3D9.
I talked to my brother and he said he has tryed running the laptop on administrator but it doesn't work I'll have to wait till we can run as administrator before I do anything I guess :/
