I'm getting a message telling me that there is an update for Calibre. To update I must first uninstall Calibre and then update. If I uninstall what will happen to my library, will it vanish and leave me with a clean slate and all my collections gone. I've spent too many hours building this and I have no wish to lose it. Can someone please tell me how to update and also how to back up my library.
Thanks for reading my woes
