I had to reinstall N360 when errors could not be fixed following a XP restore to earlier date. Programs all work properly. Version is 5xxxx, the latest. I was asked to do online backup. Previous backup online contains documents and settings but no photos. A totally new backup set was made instead of recognizing the previous online backup. Why? XP media version, IE 7. I would appreciate an answer to what happened and how to avoid using up expensive backup space.
