Thanks for your input. Surely any product where an update has been provided should be accessible ? I had Lightroom 5.2 with the update on my old computer, but I have had to purchase a new computer -hence the need for this. Any further help would be appreciated.
Rob, Many thanksfor your help and suggestion. i have been successful in downloading the 5.7.1 edition of Lightroom which, on checking back is actually the latest edition I had on my old computer. This more than meets my needs. Very gratefull for your help.
