Thunderbird stopped downloading new messages last Friday, inbox constantly spins. After a long search I got to the database file that needs to be deleted, but when I try that the computer says the file is in use and countermands the delete. I also went into the program and found profiles and tried to fix the inbox, but it is empty and the inbox still spins. If I could export my contact list I would uninstall the program and start again. Thanks for any help.
