Brawl freezes with beeping sound when loading any custom texture

[NeOsZ]

Hey guys, I'm relatively new to brawl hacking and I'm experiencing a problem loading custom textures. The first day I wanted to start hacking my brawl, I downloaded riivolution and an .xml file for it using the x:/ssbb method, inserted a few textures and stages and it worked like a charm. Then all the sudden, every time any custom texture or stage was meant to be loaded, brawl would crash with that ear-exploding beeping noise. I tried reformatting my sd card, uninstalling/reinstalling riivolution and I even went as far as loading my bootmii backup from before I installed any homebrew whatsoever. I then reinstalled all my mods, cios and everything, and after I finally reinstalled riivolution, I loaded it up, only to have it crash upon loading a custom texture. Does anyone know what could be going wrong?

Check your files.  You might have a file that's corrupt.

Yea like mnsg said...  did you add any files the day it stopped working correctly?
