I hope somebody can please guide me where to look for the information that I need. I download lots of books from Amazon and have for quite a while. I use calibre to convert them to epub and remove drm. But now I find that the drm removal isn't working?? I recently updated calibe to version 2.18 if that makes a difference.Do I need to get new plugins or something like that...and where do I look for that? I am currently using the older ones that I got from alf. I think I do need some advice here
