James Schuyler Houtsma on "Audio URL errors"

I recently uploaded a post with 5 audio links to a podcast. I chose the Embed Media Player option and all worked fine until just now when instead of the media player it says "Audio: please specify correct url".

I also had problems recently with inactive embedded media players, which are also now missing.

Here is the link to the missing player:
http://themsureporter.com/october-movie-podcast/

Here is the link to the inactive ones that are also missing:
http://themsureporter.com/mid-summer-movie-podcast/

Any assistance would be appreciated.

Thanks!
