Hacking Yet Another WAD Manager Mod Problem: Black Screen When Opening the WAD Channel

[ItsMeIvan]

I downloaded a loadstructor WAD with YAWMM, it worked, but when I open the WAD, it just gives me a black screen, the game is New Super Mario Bros Wii,
if I don't find a fix in a few days, I will just delete the wad, I can always just use USB Loader GX
