I purchased Creative Cloud for the purpose of using Photoshop, so it was the first program that I downloaded. It gave me a "You can't open the application 'Adobe Photoshop CC' because it may be damaged or incomplete." Since then I have tried: uninstalling and reinstalling Creative Cloud, uninstalling and reinstalling Photoshop CC, and neither of these things has helped. I still am unable to open Photoshop CC. I run Max OS X 10.8.3 on a 2.7 GHz i7 processor, with 4 GB RAM, and I have 150 GB of hard drive space open. If anyone can help me with it, I'd appreciate it.
