Podcasts not playing

Hi:

I have been using Seriously Simple Podcasting during the last 2 years and no problem. However, i’ve realized (i really don’t know when) all my episodes are not playable right now.

I’ve been checking cache options, and i have exclude the podcast root. Clean cache and no luck. I’m uploading the mp3 files in my hosting and then use the link in the Episode edit page. It worked but now, i don’t know why, not.

Am i missing something?

Thanks!
