I'm having the same issue. When I start PS CC 2014, it crashes probably 5 seconds after it loads up. It doesn't give any error message, just says "Adobe Photoshop CC 2014 has stopped working", and that's it. I tried starting it with CTRL+SHIFT+ALT to delete the settings file to see if that helps; it doesn't.
I should add that I'm using Windows 7 64-bit.
