Silvertone, Yes I did try it and it too was to be installed over previous version but that is all solved now as Gail sent me a link to a full install version of 2009.5 which I have already downloaded and installed with success. Have only to add in my backed up files of my own creation and get on with it. PG music has come through again and I am so grateful to them and all of you for your concern and suggestions.
