I am 99.9999% sure that Victor has abandoned this app.
As things have changed (with torrent directories, etc.), this has not kept up. I think its idea is GREAT and some other folks appear to have forked the source code to fix the bugs. But, nothing has come of it.
It seems there is an issue with TVShows interfacing with The Pirate Bay (considering this is the primary source used for downloads.) However, if you change a setting, it seems to be able to pull magnet files for the downloads correctly.
Go to TVShows in the System Preferences (under the Apple menu).
Select "Prioritize Magnet links..." (about half-way down)
Now try downloading a missed episode by clicking a subscription (a show) and clicking the download icon (down-facing arrow) on the left for a past episode.
Unfortunately this takes some automation out of the process, but we may simply need to get into the source and change the Pirate Bay priority to something like KAT.
