It is a while I can not use your plugin. It always throes error. I suspect there is some kind of issue in its DB or Calibre DB.

I would appreciate if you could help me to find it and solve it.
The error is always same. It demonstrates always at File "calibre_plugins.annotations.annotations_db", line 241, in capture_content. It is triggered either when adding annotations into calibre:

calibre, version 2.68.0
Error fetching annotations: <p>Unable to fetch annotations from Amazon Kindle.</p>

Traceback (most recent call last):
  File "calibre_plugins.annotations.action", line 289, in fetch_device_annotations

  File "calibre_plugins.annotations.annotations", line 251, in merge_annotations
  File "calibre_plugins.annotations.annotations_db", line 241, in capture_content

or in customize plugin when moving from one column to other :

I looked at the code and the line 241 is:

this_ua.highlight_color = ua.find('table')['color']

I do not know enough about python to understand this fully. Maybe @davidfor can help?
