The project still opens, but the program monitor is frozen (stays black) and I cannot edit my sequences anymore. Also the red/yellow/green 'render bar' in the top of the timeline has disappeared. Rendering the sequence doensn't work. My last working backup is from 3 days ago, so switching to that is not realy an option. I tried to re-install the program (CS6 on a Mac 10.7), but stays the same. Other project do still work. New projects as well.
Is there anybody who can tell me anything about the above error message or knows a fix for this? It would realy help me.
