Reset the Creative Cloud desktop app to solve login and licensing issues

The Adobe Creative Cloud desktop app was killing me until I finally thought to look for and find this: “The Creative Cloud desktop app has a key command that will relaunch and reset the application.” On Mac OS X, it’s Cmd + Opt + R. It takes care of “general weirdness.” In my case “general weirdness” was a blank window and a perpetual slow-grind “loading” wheel, a message that it was slow with an option to relaunch (which just brought more of the same).
