Yesterday, all of a sudden my calendar showed empty. There was an unexpected reboot & all the entries were missing. I couldn`t figure out what went wrong. I tried restoring the calendar entries (thru ovi suite) from a back-up which is 3 months old. It showed successful restore but the old items are still not showing up. On searching the forums for help, I couldn`t find out any solution to this. I came to know that all the items of calendar are stored at /home/user/.calendar/calendardb.backup. This file shows the last modified date/time of one day before it crashed. Can anyone help me how to restore the items from this file, or any other way?
