Choosing Sound Files with the ogg extension while creating a new Voicepack causes an error:

An error has occurred: This is a sound related error. Please make sure your sound drivers are up to date. You may want to go under options and change the audio device being used. See our forums for more troubleshooting.

So I get this error message and sometimes the Stat Tracker crashes too. I changed my sound device from "default" to "USB Headset", but it didn't solve the problem.

Edit: Looks like there might be a problem with the sound files I'm trying to choose and playback. I converted them from mp3 format to ogg format in Audacity 2.1.1. Is there something I have to pay attention to while converting them? Because ogg files from other voicepacks play without a problem. (Is Audacity 2.1.1 saving files as a newer/different ogg format?)

I'm using Windows 7 Ultimate and Recursion Stat Tracker Version 0.10.3.3
