We are seeing reports that the Nvidia CUDA 5.5.47 update released today addresses crashing problems introduced by the CUDA 5.5.43 update.
So, if you have an Nvidia GPU, please update your drivers to use the most recent version of the CUDA driver.
IMPORTANT: DO NOT install CUDA drivers on computer systems that do not have an Nvidia GPU! If you have done so, then you must uninstall the CUDA framework from your system. If you have CUDA software installed on a computer that does not have Nvidia CUDA-capable hardware, bad things happen, including crashes.
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.
Feel free to let us know on this forum thread whether or not this update is working for you.
Also, make sure that you have installed the most recent updates for your Adobe video applications.
