1 Try creating a new, empty project and
importing your problematic project.
2 Look through your Auto-Saves for the most
recent, intact project file.
The Auto-save files also crash the same way the main project file crashes. I get a serious error message that I can't read fully because it disappears as soon as it pops up. Attempting to import the project with a new project also crashes Premiere and gives me the same serious error message.
Reboot the machine, then try opening PP again.
Tried that. No avail. I also can't import the project into After Effects without After Effects crashing. If I delete render files will that maybe help open the project? I think it's just too big to open. Premiere and my harddrives are working just fine, it just seems to be this one project.
