I think I've installed Wootumblog correctly, but I've noticed that it won't play the entire MP3 when I create an audio post. This happens whether I upload an MP3 or link to one from another site. I checked the media library, and the entire tracks are uploaded. There also isn't a specific time they stop -- some MP3s play for 1m30s, others for about 3s. Anyone know what's going on?
