After updating to 8.5 I can no longer save books in Edit Metadata or convert books. Also book viewer does not work for books not in Calibre. The error I get is:

calibre, version 0.8.5
ERROR: Unhandled exception: <b>OSError</b>:[Errno 13] Permission denied

Traceback (most recent call last):

Calibre was working great prior to this. What's the problem. anyone?? I've tried going back to 8.4 but that didn't work either. Calibre also deleted some book formats when the conversion failed.
