BrawlBox always crashes when modifying character SFX then saving!

[LolHacksRule]

I was using BrawlBox completely fine before, but now anytime I modify a SFX clip then save the .brsar, BrawlBox always crashes with the "BrawlBox has stopped working" message. I tried to delete all data from BrawlBox and the registry entries then reinstalled BrawlBox on my PC to attempt to fix this and this problem still exists! Any way to fix this so BrawlBox works correctly again?

PC: Windows 10 Home (x64) SD: Lexar Multi-Use (2GB) Game: Mario Kart Wii (NTSC, Disc, CTGP My Stuff) Console: Black Wii U 5.5.2U (NTSC) BrawlBox Version: 0.68d/0.77
