FeralHeart.exe has stopped working! What did I do this time?

Hi again, everyone. This is like my 4th time doing this? Anyways, I was getting some of Glave's particles into my game and I realized that the Grasshopper, Flys, and the Butterflies didn't work but everything else did. I simply shrugged it off, no biggy. I'll just go see what happened. So, I pulled up my FeralHeart folder and went to the Particles sub-folder.
Oh, look! It's a Material file, why don't I just go put that in my Material folder! *Idiot, don't do it!*
So, I close down FeralHeart and restart, thinking everything's dandy. It's not. Nope. My game frezes and a message pops up "FeralHeart.exe has stopped working" with a gray background.
I combed through my files and couldn't find anything with _1/_2/etc.
I really don't want to delete it, because I've way to many files on there.
I've also tried running it as administrator, but that doesn't work either!

Did you delete any files?
Did you also look for files at _0 at their ends?
these are the 2 questions I would love to ask you with this problem.

Since you had the material file in Particles, make sure it isn't there any more and that its just in your Materials folder. If it is still in your particle folder, then delete it. The same thing happened too me and when I did this, it was fixed.

@WolfKate  I didn't delete any files that I know of, and I did look for those pesky _0 files, too.
@BBT  I just tried that and the same thing keeps coming up. ;u; What really sucks is that I just got a new high rank in an RP yesterday.

I did it! But, I had to delete the game and then re-do it. No biggy, I saved my important files. But now I can't get onto my characters. Sure, I can log in but when I try to play my charries, the game does a total brainfart.
