My Ubuntu-installation stopped working correctly, but I managed to make a copy of my personal files. Now I'm trying to setup Thunderbird + Lightning on an another computer (Windows 7). Mail no problem, just copying correct folders of TB profile. But what about my events and tasks? I see a map called 'calendar-data' with file 'local.sqlite', but just copying this to the new environment doesn't give me back my events and tasks. Yes, I did add the Lightning add-on of course.
Mozilla lists tyhe following files at http://kb.mozillazine.org/Files_and_folders_in_the_profile_-_Thunderbird for the Lightning calendatr:
- local.sqlite (which you've already brough over)
In addition, you can import any .ics files that you might have added.
Let me know if this fixes the issue.
