We are seeing reports that the CUDA 5.5.47 driver update released today addresses the crashing problems introduced by the CUDA 5.5.43 driver update.
So, if you have an Nvidia GPU, please update your drivers to use the most recent version of the CUDA driver.
On Mac OS, you can update your version of the CUDA driver from the CUDA panel, available from the Mac OS System Preferences. For CUDA downloads, see the Nvidia website.
Also, make sure that you have installed the most recent updates for your Adobe video applications.
