I have tried opening the project file directly, or opening from the splash page. I also tried importing the project or even select sequences into a brand new project. All do the same thing
Some trouble-shooting measures that I've tried:
Trashing Media Cache
Rescan for plug-ins
Importing project or sequences into brand new project
Reseting permissions to R/W for multiple "Adobe" folder, including enclosed files
Still having this problem? Please let us know.
