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
