Do you have more than one episode out there? Check your My Media to confirm. It looks to me like your 11 May episode is the only one, though you mention you had previous postings.
Should the previous episodes be missing, do you have local copies you can upload to restore them?

I guess I should add that the quality of your recordings is abysmal! I was just barely able to make out - maybe - some of your words. It sounds like you might have a nice voice, hidden behind all that noise and echo. We have to fix that.
I can't believe you listened to that, so is it fair to guess that you are recording it via the POM web software? I strongly recommend you use Audacity (cross-platform and free) or GarageBand (Mac-only, small fee) to record and edit your episodes.
The level of echo strongly suggests you are listening as you record, using the system's speakers sitting near the microphone? Try turning the sound off, or using a head-set.
Lots of static suggests ... all sorts of possibilities. A really bad microphone, bad plugs between the mic and the computer, a bad mixer ... something is adding noise between you and your recording.
If we can eliminate these problems, we may be able to hear your voice as it was intended. Let's get your message out there for the world to hear.
