I have a Kindle Paperwhite which is my third Kindle. I have used Calibre for five years and love it. But today after sending four books to my Kindle and having them show as being on my Kindle I ejected my Kindle but couldn't find the books. I connected my Kindle again but this time couldn't get Calibre to recognize it. Finally stopped using a hub and connected directly to my Mac. Got Calibre to acknowledge my Kindle but it still showed that I had loaded the books from Calibre to my Kindle even though I know they aren't there. I tried loading one again and still no show. I have never had any problems with Calibre before and the thought of it no longer working for my Kindle....I can't fathom it. Does anyone have a suggestion of what might be wrong?

Thanks
