The software was working correctly when I shut down my Mac 3 days go. Now I can't launch Premiere Pro CC, it just sits on the splash screen. Adobe Prelude does the same thing but all other Adobe software launches correctly.
My apps are all up to date just like they were when I shut down last week.
I'm on windows, however, one indication can be a plugin. Watch the plugins as they load in the application, view-able on the bottom of the welcome/startup screen. Which plugin does it get stuck on?
You could try to launch PPro with preferences reset (press the Option key while starting).
How are you starting up the application? From the Icon or via a project file? Whichever your doing, try the other method.
I did the Mac OS update that's been available for a couple of weeks and everything worked after that.
