Prevent Delete Worksheet

An old post provided the following macros that purportedly prevent users from deleting a worksheet. Unfortunately, it also makes it so you can't delete ANY worksheet in ANY file, which is of course not what was intended. Need figure a way to remove this nuisance? All attempts to delete a sheet keep looking back to the offending workbook, even though the macro has since been deleted from it.

Try pasting the following two event procedures into the Help sheet module:

'==========================>>
Private Sub Worksheet_Activate()
Dim CB As CommandBar
Dim Ctrl As CommandBarControl
For Each CB In Application.CommandBars
Set Ctrl = CB.FindControl(ID:=847, recursive:=True)
If Not Ctrl Is Nothing Then
Ctrl.OnAction = "RefuseToDelete"
Ctrl.State = msoButtonUp
End If
Next
End Sub................
