I use windows 10, the weird thing is when I installed LR lite the program was working just fine. When I purchased LR and installed the full (newest) version I am getting a blank video screen. I already checked to see if I have the "KB3099406" update, but it isn't there. I already send a diagnostic report but am still waiting on a reply. I paid a lot of money for the full program and am still unable to use it
