It looks like my brain got muddled from all the dithering that I was doing trying to get the calibre plugins to download correctly. My errors...I had only done this once before and that was years ago...so I forgot a few things. And then I completely forgot how to import the ebooks the right way into calibre. All seems to be working right now and I can convert my ebooks again...if I remember to take my time and do it the right way!
