I'm not sure I'm in the right place but I have a problem opening my Thunderbird email. It keeps telling me that it's open and to close but nothing happens. I can't close it and it's not actually open. I've rebooted my computer but Thunderbird still insists it's open. What can I do? I can't access and folders or emails. Should I uninstall it and reinstall it? Really hope you can help me
