iTunes Error

Hi,
My podcast RSS feed was working fine with iTunes. After the latest update, I began to receive an error in iTunes and now my episodes don’t get updated anymore in iTunes. I contacted their support and this was their response:

I have reviewed your RSS Feed URL, and I am not able to find a cause for the error on our end. Any issues within a RSS Feed are at the provider’s discretion to resolve to ensure that it is functional. I would suggest that you reach out to your host for assistance in resolving this error.

Here is a link to the feed: http://wabcbizradio.com/podcast

Can you please help me resolve this asap?

Thank you!
