I have installed "deviantART Favorites Downloader" and read the help files but am unable to get it to work. The progress windows show up but vanish immediately. I think this is due to the "Searcher" under "Preferences > Options > Advanced > Searcher".
All options are greyed-out except for "Hello World Searcher". The documentation says that the "RSS Searcher" should work and, indeed, be the primary method used. However, it is greyed-out and cannot be selected.
Where can I download and how can I install this searcher?
