When I opened my Lightroom 5.7 software, I got a "Lightroom Update Software" Notice. So I click on the "Download" button to download the new update but it just took me to the Lightroom website from which I had no idea where to go to get the software update (http://www.adobe.com/products/photoshop-lightroom.html). How or where do I download the software update? It's always downloaded it for me automatically before. Thank you!
