I recently got a PS CC trial, and when I open it, it crashes immediately. Then when I open it again a dialog comes up saying there's a problem with the display driver and graphics have been temporarily disabled. If I enable them, the cycle starts again. Right now, I can barely use the program because everything is so pixelated.
Its hard to give you any advice without knowing what OS you using and what graphics hardware you have and the device driver version you have for your video adapter. Does you machine meet CC requirements?
Yes, and like the warning says, you need to update your video card driver from the GPU maker's website so you'll have the latest bugfixes to the driver.
