The Thunderbird icon has changed to a file icon. It said to reboot, I did it three times. No matter what I do with Thunderbird it says: Your computer must be restarted to complete a previous upgrade of Thunderbird. I was going to uninstall and reinstall but the same message comes up. I also tried a few things from a similar post but nothing.
