My podcasts have stopped appearing

Question

I have been publishing podcasts for four years. Suddenly last month the new ones stopped appearing. I suppose something has become corrupted in the xml code, but I am unable to find it. Do you have any ideas? The podcasts are for Knox United Church, Calgary, Alberta, Canada.
Thanks.
