This morning whenI tried to open Lightroom I was told I needed to download the update. After doing that I tried opening Lightroom and it will not open. It asks for my serial number. I don't know what it is. I pay $9.99 a month for CC2014. I was able to get it to open by clicking on the 30 day free trial; however, I pay $9.99 a month and Lightroom is included for that price. Thanks for your help - Russell Colby
Uninstall the "stand-alone" Lightroom, and install from the CC Dektop app.
