More than 10 second car sounds freeze the game (Help?)

Hello everyone! Right now I'm having a huge problem trying to import a custom sound into my SHAR mod.

To my dismay, I found out myself that car sounds must be shorter than 10 seconds long (But I could be wrong, which I probably am...)

Of course the sound file I used was a longer version of a police siren that was exactly 00:14:280 seconds long. Every time I launch the game and get past the main menu, once the game goes to the loading screen, it freezes in the middle of loading and doesn't automatically close the simpsons.exe application! (I have to hit my windows button and close the application manually)

If anyone knows a way to make the game accept longer sound files in the "carsound" folder of my mod, let me know!

What I forgot to add: the sound file I am using a 16-bit, mono, .wav file with a sample rate of 24000, and there is nothing wrong with the wav file itself....
