Because this forum is for beginners trying to learn the basics of Photoshop, I'm moving this discussion to the Adobe Bridge forum where your question will receive more specialized attention.
In Bridge click edit/preferences/startup scripts. Make sure there is a check mark for at least Bridge and Photoshop.
Also, make sure you are runnning CS6 Bridge and CS6 Photoshop. Many forget that they have the old Bridge version set to run in the background and so CS6 will not start.
