Hi. I updated to latest version of Zotero and when I try to use stand alone my I get the message Zotero no responde (Zotero does not respond). I have tried ininstalling and re-installing and it still does not work. When I reloaded the original version I was told that I needed to update. My references still appear on the website Zotero, but most of the attachments are only on my compute and I cannot search them at present.
Help needed!
