I have Libronix 3.0g, and recently ran the update feature. It told me that there were updates to certain books I have in my library so I clicked to update them. When I restarted Libronix, I checked those books that were updated, I found that they were all marked with highlighting that I did not do, and now it will not let me remove the visual markups. How do I get my books back to their original form?
