Need Help With Custom Dialog, Help!

I've Done Everything Here: How To Add Dialogue Topic
But My Game Still Crashes, Help?


What I've Done:
Used Audicity
Made My Sound File 24000 Hz,

Saving the File As: 16-bit microsoft signed PCM

BUT THE GAME STILL CRASHES

So If You Know What I Did Wrong,
Give Me A Tutorial On How To Edit The File Correctly

Dialogue needs to be in mono
You need to set it to mono in audacity before exporting
Only music should be in stereo

Oh, OOPS!
