Hi again. Thanks for your help on this. At the moment I feel fairly sure that the problem is at the BibleStudy/my website end rather than the FeedBurner end. I say this because when I look at the validator for my original source then I see that my updates are not in there (you can see the validator's output here
feedvalidator.org/check.cgi?url=http%3a%...llbaptistpodcast.xml) The new episode is called God's Promise and that doesn't appear in the feed and as mentioned previously I have altered the email address in the podcast in BibleStudy but this isn't being updated either. I don't understand why when I write a new xml file (in BibleStudy) this isn't replacing the old one on my website. The very first time this happened I did get an error message which may be important. It said something about not being able to write something. I assumed this was a temporary error so did it again and didn't receive the error message. Thanks again for any help with this!
