'Map Maker' Won't work at all?!

[Muggery]

So, yesterday, I had completed a HM, and wanted to place it into Map maker. However, as soon as I clicked the Map Maker icon in the game, I got a 'Feral Heart.exe has stopped working' message. I have repeatedly tried restarting the game, and each time, I've gotten the same message. Every other 'Tool' works fine, minus the Movie Maker. This never used to happen, and now I've pretty much given up. Any help?
 
P.S: I am using a Windows 8 OS (Not sure if i should include this)

Make sure the map is 513 x 513 and a greyscale! Many people crash because they don't do that.

Also go into C: >>> Feralheart >> media > particles and delete any ending in a _0, _1, etc.

Also try changing your rendering system.

Also, try looking here: Click Me

Thank youu! I'm kinda sad that I will have to re-download the game, but I need to use map maker, so that's probably my best bet. :3

Make sure you save all of your preset and map files to another folder!
