After deleting and re-installing everything as dictated in Apple’s Compressor Troubleshooting Basics, I still got no batch screen until I read and did the following.
In some cases after updating or reinstalling Compressor 3, the Preview window may display a large blank space in the upper area of the window.
Take the following steps to remove the blank space from the Preview window.
1. Choose Window > Layouts > Standard 1280×800.
2. Close Compressor.
3. Open Compressor.
After taking these steps, the Compressor Preview window should appear without the blank space.
This is what fixed it for me. Cheers.
