I am not able to open Thunderbird. I get message it's already running and must be closed first, but no other Thunderbird is open according to task master. I have uninstalled it and reinstalled it but always get same message that it's already running. I did search and cannot find anything under Thunderbird after uninstalling it.

It was working fine in Windows 8 until a week ago.
