Thunderbird Showing Up Error

[Zander_121]

Whenever I am opening my Thunderbird account I am facing some error. It's a problem to work on it now. I even purchased Outlook due to these errors coming daily. I don't want to use Thunderbird. But how will get my data.
Help if anyone knows how to transfer data.
Thanxx

Moving to Thunderbird Support.

What is the text of the error message?
What version of Thunderbird?

See this article to transfer data == http://kb.mozillazine.org/Export_mail_i ... Apple_Mail
