I no longer have Live Mail on my PC, so I can't check what you are doing.
Your responses refer a lot to "importing" and very little to "exporting".
Are you in fact starting Windows Mail and using its built-in export capability to export to a safe folder somewhere on your PC. This is what I think you should do.
Or are you starting up Thunderbird and then using its import function to grab something within Windows Mail? As I recall, you can't do that. I think you have to formally export from within Windows Mail, maybe just a folder at a time. And then start Tbird and import from that saved location.
You may be doing as I suggest, but I'm not sure from reading your responses.
