I believe you already made a thread about this, in which there were replies and we've been trying our best to help you. If your problem isn't resolved straight away, try to refrain from posting another thread regarding the same topic. We haven't forgot about you, we're just trying to figure out how to help. As for the problem, perhaps try this idea by Bawfle:
I'd make a copy of your FeralHeart folder and paste it on your Desktop (or just move it), and then go back and delete the FeralHeart folder you have in Local Disk (C:). When you've done this, uninstall and then re-install the game. Once you have, you can then slowly start adding back anything you wish to keep from the FeralHeart folder that you copied. Every time you add something back (a map, items, markings, etc), be sure to test the game before adding the next thing so you can identify exactly what is making your game crash.
