Lockchime help

did the custom lock chime to test it out, I got tired of lock chime #1, so I plug my usb into my computer, and download lock chime #2. I put lock chime #1 to my desktop, I downloaded the mp3 I wanted, converted it into a wav, renamed it "LockChime.wav", plugged the usb back into my car... and boom. It plays the lock chime #1. Did I do something wrong? Do I need to reboot?
