After installing this latest update of Premiere Pro to 15.0, most of my media in projects would not load. Plenty of "System not responding", endless beachballs and many force quits before I figured out how to re-install 14.9. Fair warning about removing old versions would have been nice! You'd think Adobe would do a little more research before issuing updates that don't work!
