I had almost given up hope of an update for this plugin. Really happy to see it got some attention!
Unfortunately I am getting an error where it is unable to find any results. I have tried with multiple books and combinations of title, author, isbn, etc... with no results.
A copy of the error is quoted below. Calibre is currently up-to-date as version 2.0.0.
Any and all hep is appreciated. I would love to get this plugin running again. Thanks.
