    I seem to have two copies of Lightroom 6


      I have Lightroom 6 and downloaded what I thought was an update, but was probably a full programme download. On trying to open the program I got a message saying that it could not use the catalogue as it was already in use by another application. I have tried using a back-up from a few days earlier but it will not accept it. Help!
