I have just re installed Windows Live Mail on my Windows 8.1 PC, everything else is ok, But Now I can’t Create a "New Event" in the Calendar. The Icon in the tool bar and the Calendar Menu appears "Greyed out". I have tried the "Repair" in the Control Panel, and have re-installed it. All to No avail, what do I do next?
