Today I launched up a brand new install of Premiere Pro CC 2014 (it's a trial) on a brand new iMac (3.5 GHz intel Core i7, 32 GB RAM, NVIDIA GeForce GTX 780M 4096 MB) and my project that was working fine yesterday on my MacBook Air will not play anything. The footage is all DSLR H.264. My sequences won't play, my clips won't play, my merged clips won't play, my multi cam sequences won't play. You hit play and the play button changes to a stop button, but nothing happens. I tried logging in as root but it won't play there either. All the footage is sitting on an external 4TB Lacie thunderbolt drive.
Any thoughts??
