I have a problem when I import from my camera card, light room cat 5 opens(only just noticed that bit!) I inport on to the drive and the file appears to be in the right place. When I go back to my PC later and open light Room another version opens 5.7.1 but I cant find the file I created when Iimporting. I need help sorting this mess as now I have files all over the place!
What version of Lightroom are you expecting to open?
