I got problems where premiere crashes when I work with the scopes. After that I can't open up premiere for that project I currently worked in. So I open a new project, and then open the old one, delete the colour edit and then save the project. After that it's possible for me to open the old projects that crashed. But there is still problems with the program. I can't close premiere properly without doing a force quit. But I can at least finish the project, delete it from the computer, so it doesn't interfere with other projects. That's my worktrip to handle this low-level exception problem.
