Downloaded latest verzion of thunderbird, and thr required latest version of lightning and totally lost my calendar. It disappeared and I can't find it.
Today I received a message that I should download the latest version of Thunderbird. I did. Then I got a message that my version of lightning was incompatible and needed to be updated. I tried to download the latest version of lightning and a blank email appeared with an attachment that ended with .xpi. My calendar with several medical appointments and many important dates for 6 months has totally disappeared. I have tried to locate it in my backup hard drive without success. How do I recover it? I have tried to upload the file name as it appeared but the upload icon just keeps whirring around. the attached file name is "lightning-3.3.1-tb+sm-windows-1.xpi". I have also tried the windows Recovery option for several dates but can't recover my calendar. HELP.

You have a mismatched version of Thunderbird and Lightning. Since you do not say what version of Thunderbird you are running the best I can offer is go to this link and get the correct version of Lightning.

The version of Lightning that you reference above is a Beta version so unless you are running beta Thunderbird is is not correct.
When you get a match pair of software all you important events will return.
