Many of the files for this project were imported from Final Cut Pro, but that has never been an issue. it's been weeks of flawless use. This evening, I tried opening the project and it quit unexpectedly; Error message telling me Adobe Premiere Pro crashed would I like to report it etc. I shut down the hard drives, unplugged them, plugged them back in, re-opened the project and suddenly... EVERY timeline is playing back at half-speed! All the audio is slowed down and the video stutters and moves slow. Pretty scary problem. Can't seem to figure it out. I even tried rendering the preview files. No go. Suggestions?
