No, it's not due to the ban, it's probably due to something you've downloaded. I would suggest(if you downloaded something) taking it out, and making sure you placed it right. If not, then I would leave the download out of it. Otherwise, the easy fix is to just redownload Feralheart ^^ Yus it's not to fun doing it, but that should fix your game.
If you tried this, and it doesn't work, try changing the rendering system you're on (direct3D or OpenGL). If you have a mac computer, and upgraded it, that could be the problem too. Feralheart isn't compatible with it, so you must downgrade.
If you need anything else, just ask.
