I downloaded the latest trial version of Lightroon but the computer I downloaded to was running on Windows 7 so I upgraded to the Windows 10 and then tried it and it still won't work. I also downloaded Photoshop and it works fine. When I click on it to open it pops up a window that tells me I have 29 days left in my free trial and the option to click on "continue with trial, buy or license this product" I click continue with free trial and the window closes and nothing happens.
