How to re-download podcasts

[sonarz]

I tried to download a new podcast and Subsonic gave me an error. I unfortunately did not take note of what it said. Now all of my podcasts are gone. Subsonic still knows where they should be but all of the files were deleted. All of the directories where they were stored are empty. Is there any way for me to re-download the files? If I select all the episodes in a podcast and click download, nothing happens.
