None of these solutions worked. I uninstalled CC, deleted the opm.db file, reinstalled CC, launched CC and guess what? Home never loads.
I've spent more time researching and combing the discussion groups and forums trying to get CC and CC applications working correctly, particulary DW CC which has now apparently become strictly a front end website design app. Hey, who needs Databases anyway! I rue the day I decided to switch to the CC subscription model. I've had to reinstall DW CS6 app so I can get some work done. I spent hours trying to get the Server Behavior extension to work in DW CC, closely following the YouTube video http://www.youtube.com/watch?feature=player_embedded&v=cB2vmNfcq7A. I gave up and just went back to DW CS6. Software shouldn't be this difficult for a user to, well, use. Not everyone is a tech wiz!
I didn't sign up to be a beta tester. Let me know when Adobe gets their act together. Until then, I'm done fooling around trying to get CC working correctly.
