So I managed to restore podomatic. It took a while, but we have everything back in place (and I updated the titles for all the older episodes so everything is uniform).
I apologize to anyone who experienced some issues with the podcast: Getting everything up to speed ended up causing a few more issues than I planned and we lost the latest chapter (#18 on druids) about 3 times before it settled in correctly.
Everything should be good to go from now on!
