I did not have this problem before (0.8.51). I also noticed that when searching for cover, even if there is a hit (from Duoban) it doesn't show up as a result. When I try to manually add a cover, the error above happen. Also, when the device (Kindle DXG) is plugin and recognized, the "On Device" does not appear either.

Edit: After some uninstall and manually delete the program's folder, I get it working now. Not sure what caused it before. Sorry for the false alarm.
