Okay, I took a look and I can hopefully explain what 's wrong.
You have registered the URL
http://www.realestate360live.com/feed/podcast/ at the iTunes Store as the URL of your podcast. But this URL leads currently to the page Podcasts of your blog because the feed with the slug name "podcast" does not exists anymore. You have renamed to re360 (
http://www.realestate360live.com/feed/podcast/) and that feed is working and loaded with all meta information you would like to see on the iTunes Store page of your podcast.
But currently the iTunes Store server does not known that the re360 feed is your podcast feed. It has still the old URL and since it is no longer a feed with data in a certain structure, it is not possible to download episodes after subscribing with the iTunes client software to your podcast. The information on the iTunes Store page and server are old information from the time when the registered URL was still a valid feed.
Usually when you rename a feed or when you move your podcast then you can inform the iTunes Server of the new URL by keep both (the new and the old) feeds alive at the same time for a couple of days. During this time you need to activate the iTunes:new-feed-url option in the settings of the old feed. It is also necessary insert the URL of the new podcast feed in the related input on the settings page. podPress will then add this information to the old feed and the iTunes Server will switch the URL after the next update cycle. When the server take the information from the new URL, you may deactivate the old feed.
I have prepared the podPress Feed/iTunes Settings page of your blog. If you intend to keep the new URL then you just need to activate the podPress Feed with the name "podcast" (see the last section of the settings page).
An alternative idea would be to rename the "re360" feed to "podcast" again.
