I submitted an update to Microsoft last night that will disable the new audio engine by default, so once the update is available (hopefully later today), your mp3 files will work again. I apologize for any inconvenience the update has caused. As for why the mp3 files are not playing, the new audio engine doesn't support mpeg3 layer 2 audio files (only layer 3), and it also won't load any mp3 files with special characters anywhere in the path (such as umlauts, accent marks, etc).
