HELP, I need PS to work ASAP... Thanks to All... TOM
Is this a Photoshop or After Effects question? You're in the After Effects forum.
The answer is that you changed your graphics setup/ driver and it doesn't go together with PS' OpenGL. Turn it off in the prefs and update/adjust the driver and its config. and true, you're in the wrong forum. Your question would probably long have been answered in the PS forum.
