I'm not a tech person so I'm in need of some help. Yesterday Lightroom worked fine. Today, I'm not able to export my images. It's asking me to choose an application. I want my images to go right into my Downloads, so I've chosen "Open to Other Application" and then it asks me to choose an application. When I click on it, my downloads pop up, but I cannot save this choice and my images are not downloading. What can I do to fix this? Thanks for any help.
