I keep getting a "Server Busy" alert - "This action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy server program and correct the problem." After clicking on "Switch To" the same alert appears.
How do I correct this? I cannot access LR CC.
I notice you are running LR CC 2015.1.1. Once you get LR launching again you may wish to update to the latest version – LR CC 2015.3
