It's easier for everyone, and better for you (you learn the code) to to fix the problem yourself. Here are some solutions:
1.Simplest. Just comment that part of the code out. (Add // before the lines of code that look for the sound file in the .ini file.)
2.Add the sound file there yourself. (Copy-Paste. Simple Enough. Create folders if you have to.)
3.Chances are the sound file exists in build 23, it's just in a different place.(Change the path in the .ini to find the sound file in a different part of the folder.)
Good luck resolving the problem!
