Error codes are worthless. Leo doesn't know why companies still use error codes, because it doesn't tell the user anything. Leo says to try holding down the "option" key while emptying the trash, but that didn't work in Deanne's case. It also may be an issue related to Time Machine, and there is a tech document about it here. There is a free AppleScript called Trash It. Download and run that, and it should clear up the issue.
