Feral Heart

Hello

So...yesterday I made myself a map on Feral Heart, and there was no problem, I made a video on it, etc. But like 3 hours later when I opened up the game and it loaded until I had to choose the Rendering Subsystem, and clicked okay and the game crashed there. I tried again, thinking it was my computer acting up again, but it crashed every time I went through the choosing, so I turned my computer off and back on, and tried again, but it kept crashing. So, I tried re-installing the game, but it still kept crashing.

It was kind of late, so I went to bed thinking my cp just needed some rest (to cool down or something) so it wouldn't keep that up, but it still doesn't work and I don't know what to do. :/
