I am editing on a MacBook Pro Retina OS 10.8.2 2.3GHz 16GB RAM running PPro version 6.0.2 and am encountering this problem when trying to launch projects. The projects and media reside on an external Thunderbolt drive (I realize this isn't ideal but it has been working fine for months for numerous projects without a hiccup).
"Sorry, a serious error has occurred that requires Adobe Premiere Pro to shut down."
I have tried multiple projects on both the external and internal drive, same problem, and even tried creating a new project on the desktop and importing a sequence from previous projects, which I can do, but when I try to launch the sequence, same crash.
Anyone have any ideas? Thanks.
