Podpress not recognizing my mp3's

I’m confused – I have made 5 podcasts and 3 of the 5 are able to be recognized by the Podpress plugin. The other two for some reason lead to an error page when the user clicks on the player. Oddly, Podpress is able to detect the file size and duration but it still won’t play. In the mean time I have disabled the player for the two posts in question. The podcast page is the following:

The podcasts that do not work with the plugin are as follows:

Thanks,
