Hi, this is my story: I updated firefox and zotero, I lost the zotero data, and i recovered it by my zotero backup. but i lost some of my recent-added papers. I wrote a paper before the lost, now I need to keep working on that paper, here comes the problem: when i inserted a citation, a window popped out with a high light on a previously inserted citation "this citation is missing, do you want to insert another one?" something like that, and also I got at least two styles of bibliography style in the list of reference. I tried to select another output style, but in the list of refs, some are updated, but the rest just keep the same. I also tried to re-insert the cannot-be-updated ones, but just the same. Hope I made myself clear. Any one can help? Thank you very much!
