Feral Heart

Title says it all. I'm in the middle of making a map. I exported it and sent it via skype to the co-creator of the group using the map to give a sneak peak and show the progress. I did everything normal. Nothing out of the ordinary. But when I went to get on FH it immediately crashed. I opened it, I clicked okay on the rendering menu thing and it crashed before I even saw the KovuLKD loading picture. I tried deleting EVERYTHING in my exports to see if the exported map was the problem, and it kept crashing. I deleted all of the map files out of media > terrains and it kept crashing. I'm kind of freaking out and I really, really, really would love some help if anyone can.
