I'h having difficulty getting Premier pro CS5.5 to run. When opeing the program the splash screen is displayed and the main window launches and sits like this untill it is forced closed. All other adobe software runs.
I have tryed the following:
Premier was runing on this machine before I reinstalled windows a few weeks ago.
Seems like you've hit all the things I might think of. If no one else has an idea, the only one left may be to wipe Windows and try again.
And make sure you install nothing but what you need to edit with on this machine. No games, no office, no email - just editing and associated tasks.
