Using Mac OS 10.10.3 (latest updates installed) on a MacBook Pro retina (2014).
I've downloaded Creative Cloud and installed the software. But I tried to launch app, nothing happens. It wo n't launch. I've uninstalled and reinstalled. Won't launch. Started up in Safe Mode. Uninstalled and reinstalled. Won't launch. I paid for year's worth of Lightroom and Photoshop use, but now I can't even download the software. WTF?
