I use E-book viewer in preference to all the other viewers I've tried, for Epubs, anyway. The problem is, at the end of each chapter at most, and often much less, I get "no such file or directory" and have to quit and restart to move to the next chunk. For the book I'm currently reading, it's more like every 10 pages. This is annoying, to say no more. Is there any way to fix this? I'm on the current version of Calibre, 3.40, on an old polycarbonate MacBook running El Capitan.

Here's a typical error message, the last one:
