Figured this out yet? If not, I might be able to help you. I use PP CC6, latest version, and I’ve been having what seems to be the same problem as you for months: a recently worked on project is reopened and clips don’t show in the monitor/playhead is unresponsive/quitting premiere creates a crash that only “force quit” can resolve. This has happened to me with multiple projects already. All you have to do is repair Disk Permissions on your main drive (using the disk utility), in my case the 1TB fusion drive inside my iMac that I have my apps on (For a little background on my set-up, very simply, I use a dual 2TB Velociraptor RAID 0 set-up for all my media and my apps are on the Internal drive). Anyway, Don’t ask me how I hit upon this, it was pure luck and works EVERY TIME. It’s odd because some projects are never affected by this problem and some others are screwed from the beginning. Hope this helps! BTW: this has been happening to me since CS6, so I think its an Apple problem not Adobe.
