I'm stuck at caliber version 3.48 because my Mac is limited to OS 10.11.6. Recently got the below errors while trying to load a specific book. It opens in calibre's reader fine. I opened it in the editor and did some of the automatic repairs. But when I try and load it to my paper white I still get the following error. Any ideas?



calibre, version 3.48.0
