I have been trying, on and off for three days to download Lightroom 5 which I purchased, in good faith a full retail price version.  I have tried at various times of the day and night usually getting to about 30% downloaded once getting to 99% with 1sec to go every time out of seven or eight tries it had frozen up.  I bought this product in good faith.  I have a very expensive PC (purchased only three months ago) running Windows 7 with huge hard drives and water cooled system with more RAM than anybody I know.  This is not good enough.  When I read your numerous solutions for my problem I read about things written in words that I do not understand.  All I want is Lightroom 5 I do not want to learn all this gobble de gook...I am nearly seventy eight years old...I dont have three days to mess around with your flawed system for supplying me with a product I want to use TODAY.
