Ok, I don't know what I did, but I remember trying out new particles for it. The first particle, musical notes/bars worked fine, but then I moved on to sakura petals and autumn leaves. Unfortunatly, it didn't read and it said "SakuraPetals were not found!" so I thought 'maybe you have to restart the game...' I did that and when I tried to reopen it, it said "FeralHeart.exe has stopped working."
I took out the particles, all of them including the notes, but it didn't work. I took out an object file that I just added and still nothing. Then I tried to take out a map I recently installed...no luck. So is there anything else I can try?
